Draw two different shapes with an area of 16 square units. What is the perimeter of each shape?

- - Rectangle, 1 unit wide, 16 units long

Area = 1 x 16 = 16 square units.

Perimeter = (1 + 16 + 1 + 16) = 34 units.

- - Rectangle, 2 units wide, 8 units long

Area = 2 x 8 = 16 square units.

Perimeter = (2 + 8 + 2 + 8) = 20 units.

- - Square, 4 units on each side

Area = 4 x 4 = 16 square units.

Perimeter = (4 + 4 + 4 + 4) = 16 units.

- - Circle, Diameter = 4.515 units

Area = π R² = π (4.515/2) ² = π (2.2575) ² = 16 square units

Perimeter = circumference = π (diameter) = 4.515 π = 14.18 units
