List all the possible dimensions of a rectangle with a perimeter of 20 inches?

Question

I am in 6th grade,Btw.Also I may need some more help later on in the week.

Answer 1

The perimeter of a rectangle = length + width + length + width.

This particular rectangle has a perimeter of 20 inches. So 2L + 2W = 20.

Divide out a 2 from all terms. L + W = 10.

The dimensions can be any two positive numbers that add to 10.
