Answer:


\Huge\boxed{240ft^2}

Explanation:

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


A=(a+b)/(2) h

where a and b = bases and h = height

Knowing the dimensions all we have to do is plug in the values


A=(12+20)/(2) 15\\12+20=32\\(32)/(2) =16\\16*15=240\\A=240ft^2

So we can conclude that the area of the floor that needs to be replaced with tile is 240 ft²
