A trapezoid has bases with lengths of 1.5 yards and 4 yards. The height is 12 yards. What is the area of the trapezoid?
Georgia [21]
Answer: 33 square yards

Explanation: To solve this, we must first add both bases together, 1.5 and 4.

1.5 + 4 = 5.5

Next, we must multiply 5.5 and 12

12 x 5.5 = 66

The last step is to divide our product by 2, similar what we do to triangles.

66/2 = 33

Here's a trick.

Don't solve all the equations, you're given the answer to x so just substitute.

5/2*8+7/2=3/4*8+14

23.5=20 INCORRECT

5/4*8-9=3/2*8-21

1=-9 INCORRECT

5/4*8-2=3/2*8-4 <- YOUR ANSWER

8=8 CORRECT
