The area of a rectangle whose 1 side is 4 cm is 36 cm2, find its perimeter.

One side is 4 cm.
Area – 36 cm’2.
Let’s define the perimeter of this rectangle. We write down the resulting solution.
First, determine the length of the second side. For this we use the following formula.
S = a * b.
We express the length.
b = S / a.
b = 36 cm’2 / 4 cm = 9 cm.
This means that the length of the rectangle is 9 centimeters.
Next, we find the perimeter of the rectangle. To do this, add the lengths of all sides. We write down the solution.
P = 2 * (a + b) = 2 * (9 + 4) = 2 * 13 = 26 cm.
This means that the perimeter is 26 centimeters.
Answer: P = 26 cm.
