The length of a rectangle is 6 m greater than the width The area is 72 m squared Find the length and width?
Let the length be x+6 and the width be x:
(x+6)*x = 72
x2+6x = 72
x2+6x-72 = 0
Solving the above equation with the quadratic equation formula will give:
x = -12 or x = 6, so x must be the latter because dimensions can't be negative.
Therefore: length = 12 m and width = 6 m
Check: 12*6 = 72 square meters
