<PRE><B>Question 317158</B>
Let A = area = 63

length = x + 2

width = x

63 = x(x + 2)

63 = x^2 + 2x

0 = x^2 + 2x - 63

You now have a quadratic equation.

0 = (x - 7)(x + 9)

x - 7 = 0

x = 7

x + 9 = 0

x = -9....We reject this negative answer because distance must be positive.

The width = x or 7 feet.

The length = x + 2 or 7 + 2 or 9.

Width is 7 feet.

Length is 9 feet.
