The perimeter of a rectangular field is 300m. If the width of the field is 59m, what is it’s length

The perimeter of a rectangular field is 300m. If the width of the field is 59m, what is it’s length?

Set up the perimeter (P) of a rectangle equation given length (l) and width (w):
2l + 2w = P

We're given P = 300 and w = 59. Plug these into the perimeter equation:
2l + 2(59) = 300
2l + 118 = 300

Typing this equation into our search engine, we get:
l = 91
