Question

Find the area of the shape shown below.

Answer 1

31 1/2

Explanation:

You find the area for the triangle on top and the rectangle on the bottom. In order to find the area of the triangle, multiply 7 and 3. Then divide the product which is 21 by 2. So the area of the triangle is 21/2 which could also be written as 10 1/2. Next, you find the area of the rectangle which is 7x3. You get 21. Finally, you add the two areas to get 31 1/2. It could also be written as 63/2 or 31.5

Answer 2

31.5

Explanation:

We can add the areas together

We have a rectangle and a triangle

The area of the rectangle is

A = lw

= 7*3

= 21

The area of the triangle is

A = 1/2 bh

= 1/2 (7)*3

= 21/2

= 10.5

Add them together

A = 21 + 10.5

=31.5
