Answer:

C. 70 in^2

Step-by-step explanation:

What you do is use the formula for finding the area of a trapezoid.

A=a+b/2(h).

a=8

b=12

h=7

A=8+12/2(7)=70 in^2 is your answer.

Answer:

70 in^2

Step-by-step explanation:

You can split this shape into a rectangle and a triangle to find the area.

First we need to find the height and base of the triangle and we can find the base by subtract 12 and.

So 12 - 8 = 4

So the base is 4 inches.

Now you need to find the height which is easy since it is the same height of the rectangle which is 7 inches.

The formula for finding the area of a triangle is half of base* height

So 4*7 is 28 and half of 28 is 14.

Now we need to find the area of the rectangle and you already have the base and the height so you just need to multiply them together.

So 7*8 equals 56.

Now you need to add 56 and 12 together to get the area of the entire shape.

So the area is 70 inches^2
