Hello There!
The figure shown is a trapezoid with the following dimensions
base 1 = 12ft
base 2 = 20 ft
height = 15 ft
Given these dimensions we need to find the area
We can do this by using the area of a trapezoid formula
where a and b = bases and h = height
Knowing the dimensions all we have to do is plug in the values
So we can conclude that the area of the floor that needs to be replaced with tile is 240 ft²
