Question

Jen wants to tile the floor of her kitchen . The floor is recrangular and measures 12 feet by 8 feet. If it costs $2.50 per square foot for the materials, what is the total cost of the materials, what is the total cost of the materials for tiling the kitchen floor?

Answer 1

we know that

The area of the floor of the kitchen is equal to the area of a rectangle

so

Step 1

Find the area of the kitchen

we have

`image`

`A=12*8\\ A=96 ft^(2)`

Step 2

Find the cost

we know that

the cost is $
`2.50` per square foot

so

by proportion

`(2.50)/(1) =(x)/(96) \\\\ x= 2.50*96\\ x=240`

therefore

the answer is

the total cost of the materials for tiling the kitchen floor is $
`240`

Answer 2

Given:
rectangular floor
length = 12 feet
width = 8 feet

Area = 12 ft * 8 ft = 96 ft²

Cost of $2.50 per square foot

96 ft² * $2.50 = $240

The total cost of the materials for tiling the kitchen floor is $240.
