Question

The area of a rectangle is 24 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
Area of a rectangle = (width)(length).

Answer 1

L xW =24
L=w+5
this means 24 = (w+5) x w
24= w^2 +5w
w^2 +5w -24 = 0
(w+8)(w-3)=0
w = -8 or 3

w is positive
W=3

Answer 2

L = w+5
=3+5
+8
