What is the perimeter of a rectangle

Question

Materials: 26 feet of fencing to go around the dog park. 4 pieces of wood 3 feet long for a play area within the dog park.

Please design 2 possible rectangular dog parks. Record the perimeter and area of each park. Use the pieces of wood to design play area within the dog park. Record the perimeter and area next the play area you create

Answer 1

Hi Alicia! Look at what you know in the problem:

1. You have 26' of fence to go AROUND the dog park -- or your PERIMETER is 26'.
2. Your park needs to be a rectangle--- so you have two longer sides of equal length and two shorter sides of equal length.

L + L + W + W = P or 2L + 2W = P

You also need to fit the 3' boards in the park, so none of your sides can be smaller than 3'.

What if you choose a width of 4'...for a perimeter of 26' 2L + 2 (4') = 26'...then how big is your length?

Your area A = L x W

Once you have this design done, then choose another option.
