Question

The length of a rectangular park is 6m longer than the width. If the area of the park is 135m^2, find the length and width.

it's all about problem solving. anyone help?

Answer 1

The area of a rectangle A is equal to length (l) times width (w) or: A=lw
let x = width (w) then l (l) is (x + 6)m
A= x (x+6) = 135 m^2
x^2 + 6x = 135 m^2
x^2 + 6x - 135 = 0 Solve this quadratic for x.

Answer 2

Factor (x + 15)(x - 9)=0
x=9 and x+6= 15
l=15
w=9
