Question 386785
The area of a rectangle is 14 square meters. Find the length and width of the rectangle if its length is 5 meters greater than its width. Use an equation and the formula for the Area of a rectangle= (width)(length).
----
Let the width be "x" meters.
Then the length is "x+5" meters.
----
Equation:
A = w*L
14 = x(x+5)
14 = x^2+5x
x^2+5x-14 = 0
Factor:
(x+7)(x-2) = 0
x = -7 of x = 2
---
Only the positive solution is meaningful.
width = 2 meters
length = 7 meters
