Question

A lot for sale is shaped like a trapezoid. The bases of the trapezoid represent the widths of the front and back yards. The width of the back yard is twice the width of the front yard. The distance from the front yard to the backyard, or the height of the trapezoid, is equal to the width of the back yard. Find the width of the front and back yards, given that the area is 6000 square feet. Round to the nearest foot.

Answer 1

Answer

Front yard is 20 square root 5 back yard and height is 40 square root 5

Step-by-step explanation:

1. set up A=1/2 H(b1+b2)

2. 6000=1/2 2x (2x+x)

3. 12000=6x^2

4.2000 = x^2

5. x=20 square root 5
