A = l + w
the best dimensions would be lenght 10 feet and width 4 feet
24 - 4 = 20
20 divided by 2 (lenght) 10
10 by 10 by 4 = 24

If one length is along the house, then you still have 24 feet to divide among three sides.
Courtney
24 divided by 3 (sides) = 8
8 divided by 2 (sides) = 4
24 - 4 = 20
20 divided by 2 (sides) = 10
10 by 10 by 4 = 24 feet of fencing
8 divided by 2 (sides) = 4
24 - 4 = 20
20 divided by 2 (sides) = 10
10 by 10 by 4 = 24 feet of fencing
Ms. Sue
You don't need fencing along the wall of the house.
How about dimensions of 12 by 6, with 12 feet along the house?
12 + 6 + 6 = 24 feet of fencing.
