ii)What is the area of the garden?
B)Write an expression in terms of l that represents the width of the garden (in meters)
c)Write an expression in terms of l that represents the area of the garden (in meters).

let w be the width of the garden, then
:
2l +2w = 70
:
l +w = 35
:
A.i) 20 +w = 35
:
w = 15 meters
:
A.ii) Area = l * w = 20 * 15 = 300 square meters
:
B) w = 35 -l
:
C) Area = l * (35 -l) = 35l - l^2
