# One of the two sides of the rectangle is 5 cm and the other is 7 cm larger than it. Find the perimeter of the rectangle.

It is known from the condition that one of the two sides of the rectangle is 5 cm, and the other is 7 cm larger than it. We need to calculate the perimeter of the rectangle.

So, let’s remember the formula for finding the perimeter of a rectangle:

P = 2 (a + b).

The perimeter is the sum of the lengths of all sides of the rectangle. We know the length of one of the sides, let’s calculate the other.

It is known that the other is 7 cm larger than the first:

5 + 7 = 12 cm.

It remains to substitute the values into the formula for calculating the perimeter and perform the calculations:

P = 2 (5 + 12) = 5 * 17 = 34 cm.
