Question

A house has 3 rectangular countertops. Each countertop is 4 3/8 by 2 2/5 feet. How many square feet of tile is needed to cover all of the countertops?

Answer 1

`31(1)/(2)ft^2`

Explanation:

From the information given each of the three rectangular countertops has dimension
`4(3)/(8)` by
`2(2)/(5)` feet.

The area of a rectangular shapes is the product of the dimensions.

Each rectangular countertop has area;

`4(3)/(8)* 2(2)/(5)=(35)/(8)* (12)/(5) =10(1)/(2)ft^2`

Therefore the number of square feet tiles needed to cover all the countertops is
`=3* 10(1)/(2)=31(1)/(2)ft^2`
