Question

julia needs to buy a bathroom mirror that is 2 feet wide and 5 feet long. if the mirror sells for $5.00 per square foot, what will the total cost of the mirror be? $ submit

Explanation:

Step1: Calculate the area of the mirror

The area \(A\) of a rectangle is given by \(A = \text{length}\times\text{width}\). Here, length \(l = 5\) feet and width \(w=2\) feet. So, \(A=5\times2 = 10\) square feet.

Step2: Calculate the total cost

The cost per square - foot is \(\$5\). The total cost \(C\) is \(C=\text{Cost per square - foot}\times\text{Area}\). Substituting the values, \(C = 5\times10=\$50\)

Answer:

\(50\)
