Do rectangles with the same area necessarily have the same perimeter?Give an example to support your answer.

How I would handle this is to first look at the formula.

Area=Length*Width

Make up a rectangle's length and width. Let's say 5 feet and 3 feet.

A = 5ft * 3ft

The area is 15 sq feet.

Make sense so far?

Now, we have the following equation to make up another area with.

15 = Length*Width

Put a number value (other than 5 or 3) in for the length. Then solve for the width. Or put a value in for the width--then solve for the length. Whichever :)
