Question

Mr. Green is putting lights around 8 windows; each window is 3.5feet wide and 5 feet long. How many feet of light does he need?

Answer 1

We must find the perimeter of all eight windows. To make it simpler for us, let's find the perimeter of one window and multiply it by 8.

2*3.5 + 2*5 = 7 + 10 = 17

17*8 = 136

Hope this helps!
