- Slide 11
- Area of Parallelograms Objective: To find areas and missing dimensions of parallelograms and triangles.
- Slide 12
- Area of Parallelograms A polygon is a closed figure formed by 3 or more straight lines.
- Slide 13
- Area of Parallelograms A polygon is a closed figure formed by 3 or more straight lines. A quadrilateral is a polygon with 4 sides.
- Slide 14
- Area of Parallelograms A polygon is a closed figure formed by 3 or more straight lines. A quadrilateral is a polygon with 4 sides. A triangle is a polygon with three sides.
- Slide 15
- Area of Parallelograms A parallelogram is a quadrilateral with opposite sides parallel and equal in length.
- Slide 16
- Area of Parallelograms A rhombus is a parallelogram with all equal sides.
- Slide 17
- Area of Parallelograms The area A of a parallelogram is the length l multiplied by the height h. A = lh The length and height must be perpendicular to each other. Connected by a 90 angle. h l
- Slide 18
- Area of Parallelograms A formula is an equation that shows a relationship among certain quantities. The formula to find the area of a parallelogram is A = lh
- Slide 19
- Area of Parallelograms What is the area of the parallelogram?
- Slide 20
- Area of Parallelograms What is the area of the parallelogram? A =lh l = ?
- Slide 21
- Area of Parallelograms What is the area of the parallelogram? A =lh l = 6 h = ?
- Slide 22
- Area of Parallelograms What is the area of the parallelogram? A =lh l = 6 h = 8 What is the area?
- Slide 23
- Area of Parallelograms What is the area of the parallelogram? A =lh l = 6 h = 8 What is the area? A = 6 8 = 48 units or 48u
- Slide 24
- Area of Parallelograms What is the area of the parallelogram? Do this on your own.
- Slide 25
- Area of Parallelograms What is the area of the parallelogram? l = 20cm h = 11cm A = 11cm 20cm = 220cm
- Slide 26
- Area of Parallelograms What is the area of the parallelogram? Do this on your own.
- Slide 27
- Area of Parallelograms What is the area of the parallelogram? l = 4m h = 16m A = 4m 16m = 64m
- Slide 28
- Area of Parallelograms Find the area of the parking space.
- Slide 29
- Area of Parallelograms
- Slide 30
- Find the area of the shaded region. Do this on your own.
- Slide 31
- Area of Parallelograms Find the area of the shaded region. Area of the rectangle 25 11 = 275ft Area of the parallelogram 4 12 = 48ft The area of the shaded region is the area of the rectangle minus the area of the parallelogram, 275ft - 48ft = 227ft
- Slide 32
- Area of Parallelograms Find the area of the shaded region.
- Slide 33
- Area of Parallelograms Find the area of the shaded region. Area of the square 6 6 = 36cm Area of the parallelogram 15 8 = 120cm The area of the shaded region is the area of the parallelogram minus the area of the square, 120cm - 36cm = 84cm
- Slide 34
- Area of Parallelograms What is the height of the parallelogram if the area is 32 in? 8 in
- Slide 35
- Area of Parallelograms
- Slide 36
- What is the length of the parallelogram if the area is 17.85 cm?
- Slide 37
- Area of Parallelograms
- Slide 38
- Area of Triangles
- Slide 39
- The formula for the area of a triangle is h h l b The base of a triangle is the same as the length of a parallelogram or rectangle.
- Slide 40
- Area of Parallelograms The base is the same as length. I prefer to use the term length, but most formulas use base. The base in this instance has a lower case b.
- Slide 41
- Area of Triangles Find the area of the triangle. Do this on your own.
- Slide 42
- Area of Triangles Find the area of the triangle. A = A = 12u
- Slide 43

- Slide 48
- Area of Triangles
- Slide 49
- What is the area of the white section in the flag? Do this on Your own.
- Slide 50
- Area of Triangles
- Slide 51
- If the area of a triangle is 245 in and the height is 14 in, what is the base?
- Slide 52
- Area of Triangles
- Slide 53
- If the area of a triangle is 256.5 cm and the length is 27 cm, what is the height?
- Slide 54
- Area of Triangles
- Slide 55
- Area of Parallelograms Is a square a parallelogram? Why is the formula to find the area of a rectangle the same as the formula to find the area of a parallelogram?
- Slide 56
- Area of Parallelograms Is a square a parallelogram? Why is the formula to find the area of a rectangle the same as the formula to find the area of a parallelogram? A parallelogram is just a rectangle where a part has been moved.
- Slide 57
- Area of Triangles Is a square a parallelogram? Why is the formula to find the area of a triangle half of the formula to find the area of a rectangle?
- Slide 58
- Area of Triangles Is a square a parallelogram? Why is the formula to find the area of a triangle half of the formula to find the area of a rectangle? A rectangle is just two congruent triangles.
- Slide 59
- Area of Parallelograms Is a square a parallelogram? If x = 5 and y, x, which figure has a greater area? Explain.
- Slide 60
- Area of Parallelograms Is a square a parallelogram? If x = 5 and y, x, which figure has a greater area? Explain. The rectangle; The area of the rectangle is 5y units. Since the height of the parallelogram is less than y, the area must be less than 5y units.
