**Ms. Sue**, Monday, February 15, 2010 at 7:11pmI helped you with the last problem. Now it's your turn.

What do you think are the best dimensions?

We'll be glad to check your answer.

**Courtney**, Monday, February 15, 2010 at 7:18pmA = 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

**Ms. Sue**, Monday, February 15, 2010 at 7:32pmIf one length is along the house, then you still have 24 feet to divide among three sides.

**Courtney**, Monday, February 15, 2010 at 7:36pm24 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

**Ms. Sue**, Monday, February 15, 2010 at 7:39pmYou 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.
