Question 955975: The length of a rectangle is 5 inches more than its width. The area of the rectangle is 14 square inches. What are the dimensions of the rectangle? Answer by amarjeeth123(569) (Show Source):
You can put this solution on YOUR website! Let the width of the rectangle be x.
Then the length is (x+5).
Area of the rectangle is 14 square inches.
x(x+5)=14
x^2+5x-14=0
x^2+7x-2x-14=0
x(x+7)-2(x+7)=0
(x-2)(x+7)=0
x=2 or x=-7
x=2 is the solution.
Width of the rectangle is 2 inches.
Length of the rectangle is 7 inches.
