Question

If the perimeter of a square or rectangle is 100 meters, what are the possible areas?

Answer 1

Answer:

With an area of 100 sq m the calculation is simple as each side is 10 and you multiply by 4 giving 40m. However, sometimes the area number might be less convenient - maybe not even as square number.

If area is a, you would need 4*√a or 4√a as it’s often written.

Area of a square is 29 square units. No problem as its perimeter is 4√29 units (about 21.54)
