Question

A metal strip is being installed around a rectangular workbench that is 9 feet long and 4 feet wide. If the stripping costs ​$5 per​ foot, find the total cost of the stripping.
Total cost=

Answer 1

If the metal strip goes around the bench, then we are looking for the perimeter.

P = 2L + 2W

P = 2(9) + 2(4)

P = 18 + 8

P = 26 feet

Then, we know that the stripping costs $5 per foot, and we need 26 feet of the stripping.

26 x 5 = 130

Total cost = $130

Hope this helps!
