The perimeter of the rectangle is 72cm. Find the area of a rectangle if its lengths are 1/3.

Given:
The perimeter of the rectangle is 72 centimeters.
Its sides are referred to as 1/3.

By the condition of the problem, one side of the rectangle is three times larger.
Let the other side of the figure be x centimeters.
Then the first will be equal to 3 centimeters.
Let’s make the equation:
x + x + 3x + 3x = 72;
8x = 72;
x = 72: 8;
x = 9.
The second side of the quadrangle is 9 centimeters long.
Let’s find the value of the first:
9 * 3 = 27 centimeters.
Let’s calculate the area of this rectangle:
27 * 9 = 243 cm2.
Answer: 243 cm2.
