Question

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

Answer 1

Area of two rectangles = Area of red rectangle + area of green rectangle

= (3 × 4) + (4 × 2)

= 12 + 8

= 20 square cm

Hence, area of red triangle together

= Half of area of both rectangles together

= `1/2 xx 20`

= 10 square cm.

Hence, both triangles have the same area.
