Question

What is the area of the shape?

Answer 1

42 square units.

Explanation:

First, find the area of the rectangle, which is base*height or 7*3=21.

Next, find the area of the two triangles, each has an area of 1/2*b*h, since there are two of them, their collective area is b*h, or 7*3=21.

21+21=42 square units.

Answer 2

30

Explanation:

7 * 3 = 21

3 * 3 = 9 which covers for both triangles

each triangle is half of a square. so each triangle is 4.5 sq. units

add 21 with 9

21 + 9 = 30
