Question

A metal strip is being installed around a rectangular workbench that is 11 feet long and 4 feet wide. If the stripping costs

$5 per foot, find the total cost of the stripping.


total cost =$?

Answer 1

Explanation:

that is the same as calculating the perimeter of the rectangle (the way 1 time around the rectangle).

the perimeter of a rectangle is

2×length + 2×width

in our case that is

2×11 + 2×4 = 22 + 8 = 30 ft

the stripping costs $5 per foot, and we have 30 ft.

so, the total costs are

5 × 30 = $150
