Question

Help with math please!!!

Answer 1

Answer:

$\Huge\boxed{240ft^2}$

Step-by-step 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

$A=\frac{a+b}{2} h$

where a and b = bases and h = height

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

$A=\frac{12+20}{2} 15\\12+20=32\\\frac{32}{2} =16\\16*15=240\\A=240ft^2$

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

Answer 2

ANSWER:
240ft squared

STEP BY STEP:
1) find the area of the square (15x12)
2) find area of triangle (8x15)/2
Add these numbers up (180+60)

Hope this helps
