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

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.

Answer 2

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

$length = 12 feet width = 8 feet$

$A=12*8\\ A=96 ft^{2}$

Step 2

Find the cost

we know that

the cost is $$2.50$ per square foot

so

by proportion

$\frac{2.50}{1} =\frac{x}{96} \\\\ x= 2.50*96\\ x=240$

therefore

the answer is

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