polly wants to build a rectangular dog pen for her poodle. She has 24ft of fencing in 1 ft sections. What are the dimensions of the best dog pen for polly's poodle? explain

What do you mean by "best?" Is it a long narrow pen so that the dog can run? Or is a pen with the most square feet?

problem problem just says rectangular dog ben nothing about squar feet so i am assuming so that the dog has the most room

You might try a few possible dimensions to see which produces the largest pen.

A = 2L + 2W

A = 2(3) + 2(9)

A = 2(4) + 2(8)

A = 2(6) + 2(6)

• Geometry - ,

A = 2(4) + 2(8)
8 + 16 = 24
then you would divide the 8 and the 16 by 2 giving the dimensions

4 4 8 8 =24

is this correct

Right that would produce a pen that was 4 feet wide and 8 feet long. It would contain 32 square feet.

However a square pen that was 6 feet on each side would have an area of 36 square feet.
