The perimeter of a rectangle is 59 59 feet. If the length is 14 14 feet, find the width. Step 3 of 3 : Solve the problem by subs
Alenkasestr [34]
Perimeter = 2L + 2W  where L = length and W = width.

So we have

2*14.14 + 2W = 59.59
2W = 59.59 - 2*14.14
2W = 59.59 - 28.28 = 31.31
W = 31.31 / 2 =  15.66  to 2 decimal places
