The rectangle is 80 cm long and 80% wide. Find the perimeter and area of the rectangle.

1. Determine how many centimeters the width of the rectangle is, if it is equal to 80% of its length, and the length is 80 cm:

80: 100 * 80 = 64 cm;

2. Determine what the perimeter of the rectangle with sides 80 cm and 64 cm:

P = 2 * (80 + 64) = 144 * 2 = 288 cm;

3. Determine the area of a rectangle with sides 80 cm and 64 cm:

S = 80 * 64 = 5120 cm2.

Answer: the area of the given rectangle is 5120 cm2, and the perimeter is 288 cm.
