Question

carpet costs $12.50 per square foot. how much will it cost to buy carpet for the floor in a rectangular room that measures 20 feet by 17 feet?
$340
$925
$4,250
$8,500

Explanation:

Step1: Calculate the area of the room

The area \(A\) of a rectangle is given by \(A = length\times width\). Here, \(length = 20\) feet and \(width=17\) feet. So, \(A=20\times17 = 340\) square feet.

Step2: Calculate the total cost

The cost per square foot is \(\$12.50\). The total cost \(C\) is \(C=\text{Cost per square foot}\times\text{Area}\). Substitute the values: \(C = 12.50\times340\).
