Question

FEEEEE

Order
We need a rock
garden with a
perimeter of 24 feet
and an area of 20
square feet.
Length:
Width:

Answer 1

P = 2L + 2W
A = LW

24 = 2L + 2W
20 = LW

Solve for L or W and plug in

2L = 24 - 2W
L = 12 - W

2 = 12 - 10

Length = 2
Width = 10

Check
A = 2*10 = 20
P = 2*2 + 2*10
P = 4 + 20 = 24
