Question

What’s the area of the triangle??

Answer 1

Hello!

The formula for a trapezoid is A=0.5h(a+b) where a and b represent the two bases. If you look at the trapezoid sideways you see two bases, 20 and 16, and a height of 24. We will plug this into the equation.

A=0.5(24)(20+16)
A=12(36)
A=432 ft²

I hope this helps!

Answer 2

Note that one side is 20 ft, and the other is 16.

This means that the side that is part of the triangle is 4 ft.

The measurement is still the same for the triangle's height.

Find the area of the rectangle:
24 x 16 = 384
Find the area of the triangle:
4 x 24 = 96

Add the two numbers together:

384 + 96 = 480

You're answer is (C)

hope this helps
