Question 364563: Please help me with this Applied Problem:
Every cross section of a drainage is an isosceles trapezoid with a small base of 3 feet and a height of 1 foot. Determine the width of the larger base that would give the ditch a cross-sectional area of 5ft^2.

Every cross section of a drainage is an isosceles trapezoid with a small base of 3 feet and a height of 1 foot. Determine the width of the larger base that would give the ditch a cross-sectional area of 5ft^2.
--------------
Area = (h/2)(b1+b2)
---
5 = (1/2)(3+b2)
10 = 3+b2
b2 = 7 ft
