Jane is replacing carpet. She bought 143 square ft of carpet. If the length of carpet is 13 feet what is the width?

Hi there,
Perimeter of rectangle
= 2 x Width + 2 x Length
190 = 2(53) + 2(x)
190 = 106 + 2x
2x = 190 - 106
2x = 84
x = 42 feet
Length = 42 feet.
..............
Area of carpet = length x width
143 = 13 x width
Width = 143/13
Width = 11 feet
..............
Hope this helps :-)
