Question 2:

Now you find the area of the two rectangles Sadiq is talking about. What is the area of the red triangle? Explain.

Answer:

There are two rectangles. The orange rectangle contains 12 complete squares and the green rectangle contains 8 complete squares.

Thus, area of an orange rectangle = 12 square cm

Area of green rectangle = 8 square cm Area of the orange portion of a triangle = (12 ÷ 2) square cm = 6 square cm

Area of green portion of the triangle = (8 ÷ 2) square cm = 4 square cm Area of red triangle = (6 + 4) square cm = 10 square cm

So, the area of red triangle is 10 square cm.
