Recognize that rectangles that have the same area can have different perimenters.

Question

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 :)
