If the perimeter of a square is 80' then each side must be 20' in length. (4 x 20 = 80)

The area of a rectangle is obtained by multiplying the length by the width.

A square is a rectangle with all four sides of equal length therefore the area is two lengths multiplied together.

20 x 20 = 400 sq ft is thus the area of the square.

What is the area of a boxing ring with the maxium perimeter of 80 feet?

You don't mean the "maximum perimeter".You can keep the perimeter of 80 feet, and shape the ring to make the areaas close to zero as you want it (but you can never make it exactly zero).What you really want to ask is: What's the maximum areayou can make with aperimeter of 80 feet ?If you play with it for a while ... which you really should do ... you'll find thatthe greatest area you can make with any perimeter is a circle, and the nextgreatest is a square, with 1/4 of the perimeter on each side.So for your boxing ring and 80 feet of ropes, the square is (20-ft x 20-ft), andthe area is 400 square feet. That's the biggest possible area.
