The area of the rectangle is 36 centimeters squared, and the length of one of the sides is 4 centimeters. Find the perimeter of this rectangle.
Given:
The area S of the rectangle is 36 cm2.
The length a of one of the sides is 4 centimeters.
Let’s calculate the length of the second side of this figure:
b = S: a = 36: 4 = 9 centimeters.
Find the perimeter of the quadrangle:
P = a + a + b + b = 4 + 4 + 9 + 9 = 26 centimeters.
Answer: The perimeter of the rectangle is 26 centimeters.
