The perimeter of a rectangle is found by multiplying the length by 2 and then adding that to the width multiplied by 2.


The length is 7, multiplied by 2 = 7x2 = 14.


Subtract that from the total perimeter:

42 - 14 = 28

The length of the 2 widths is equal to 28, to find the length of 1 width, divide that by 2:

Width = 28 / 2 = 14


The width is 14 feet.
