Question

The front podium is in the shape of a trapezoid with base lengths 4 and 8.5 feet. The height is 2 feet. A gallon of paint covers about 350 square feet. How many front frames of a podium can Lillian paint with 2 gallons of paint?

Answer 1

The trapeze area is:
 A = (1/2) * (B + b) * (h)
 Where,
 B: major base
 b: minor base
 h: height
 Substituting values:
 A = (1/2) * (8.5 + 4) * (2)
 A = 12.5 feet ^ 2
 For two gallons of paint the number of trapezoids is:
 N = (2 * 350) / (12.5)
 N = 56
 Answer:
 Lillian can paint with 2 gallons of paint 56 front frames of a podium
