A trapezoidal room is to be tiled. The bases are 90 feet and 100 feet, and the
height is 30 feet. What is the cost if the tile costs $1.10 per square foot? 

First we average the bases by adding them and taking half

adding the bases gives 90+100 = 190
Dividing by 2 gives 95 for the average base

So we plug in the formula:



Then we multiply by $1.10 per sq. ft.
