STEPS
1. Measure the total area (25cm2)
2. Measure the area of the bigger space of the white squares (12,5 cm2).
3. Measure the area of the other space of the white squares (2,5 cm2).
4. Add the areas of the white space (15 cm2).
5. Measure area of the red triangle, subtracting the total area minus the area of the white space (10 cm2).
Step 1 = 25 cm2
Step 2 = 12,5 cm2
Step 3 = 2,5 cm2Step
4
=
10 cm2
Step 5 = 10 cm2
R: THE AREA OF THIS TRIANGLE IS 10 CM2.
