Find the perimeter of a rectangle if its area is 72 systems squared, and the ratio of adjacent sides is 1: 2.

Given:
rectangle, S = 72 centimeters
Find: Perimeter of a rectangle
Decision:
We solve using the equation
One side = x
other = 2x
Area =
x * 2x = 72
2x ^ 2 = 72
x ^ 2 = 72/2 = 36
x = sqrt (36) = 6 – one side
6 * 2 = 12 – other
Perimeter = 2 (6 + 12) = 36
Answer P = 36 centimeters
