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?

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
