Find the dimensions of a rectangle whose width is 6 miles less than it’s length and whose are is 55 square miles.
SSSSS [86.1K]

area = width * length

or

A = W * L

55 = W * (W+6)

solve for width:

0 = W^2 + 6W - 55

this is a quadratic and has two solutions -11 and 5

a length can only be non-negative so discard -11.

width W = 5 miles

now the length is 5+6 = 11 miles
