Question

PLEASE HELP ME THIS IS URGENT EDMENTUM MATH STUFF, PLEASE ANSWER IF YOU KNOW.

Type the correct answer in the box.

The area of the figure is ____ square units.

Answer 1

Answer: 132 square units

Explanation:

Area of a trapezoid:

a = top base; b = bottom base; h = height

`A=(a+b)/(2)+h`

Find the bases and the height:

b: 21 (given)

h: 8 (given)

a: find from the bottom

need to find the only not given value by subtracting the values we know. (this might be a little confusing but I think it'll be easier if you look at the original picture)

21 - 9 - 3 = 9

add the new number with the given length of the top base

9 + 3 = 12

Substitute the values into the equation:

`A=(a+b)/(2)+h\\`

`A=(12+21)/(2)+8`

(I used a calculator to find it out)

Area = 132 square units
