If I am not mistaken the inequality would be 45x is greater than or equal to y since the minimum would be 45 minutes a day.
Given:
Width of the rectangular yard = x feet
Length of the rectangular yard = x+4 feet
Perimeter of the rectangular yard is:

Perimeter of the yard = 84 feet
To find:
The length of the rectangular yard.

Answer:
Step-by-step explanation:
Solve simultaneously
-5x-3y=9
4x-187-54=0
4x=241
x=60.25
To get y
Substitute for x in equal one
-5(60.25)-3y=9
-301.25-3y=9
-3y=9+301.25
-3y=310.25
y=-103.4
