George uses 114 feet of fencing to enclose a rectangular garden whose length is 21 feet longer than it’s with what are the dimensions of the garden

Answer 1

Let's start with the basic equation for perimeter:

2x + 2y = Perimeter

Letting x be the length and y be the width:

x = y + 21

2(y + 21) + 2y = 114

2y + 42 + 2y = 114

4y + 42 = 114

4y = 72

y = 18

The width is 18 feet.

The length is 39 feet.
