Find the area of each figure. round to the nearest tenth if necessary .

We first would divide the Pentagon into two shapes, one a square and the other a triangle. To find the height of the triangle we must minus the 15cm to the 10cm, which gives us 5cm.

5cm= height of triangle

7cm= base of triangle

Then, apply the area of triangle formula

which is: A=(b×h)÷2

so the area would be 17.5cm squared.

For the square, 10= height and the 7=base

The formula for rectangles is:

A=b×h

so, the area is 70cm squared.

if you want the total area add the two area together, which equals 87.5cm squared.

I hope this helps.

a is the right answer
