Question 1031851
The perimeter of a rectangular garden is 60 m and its area is 225 m^. Find the length of the garden. Use L = length and W = width.


L*W=225
L= 225/W

2(L+W) = 60

L+W=30

225/W +W =30

225 +W^2=30W

W^2-30W+225=0........................equation
L^2-30L+225=0

(W-15)^2=0

W=15 

Width = 15
Length = 225/15 =15 m
