Question 1060872
The length of a rectangular garden is 5 m greater than the width.
L = (w+5)
:
 The area is 66 m^2
L * w = 66
Replace L with (w+5)
(w+5) * w
w^2 + 5w = 66
a quadratic equation
w^2 + 5w - 66 = 0
Factors
(w+11)(w-6) = 0
the positive solution
w = 6 m
You find the length, then find the area.
