You are given a rectangle with sides a and b. Find the sum of the lengths of sides a and b, if the perimeter is P = 188 cm?

We need to find the sum of the lengths of the sides of the rectangle.

From the problem statement, we know that the perimeter of the considered rectangle is P = 188 cm.

We know that the following formula is always used to find the perimeter:

P = 2 * (a + b)

where

P is the perimeter of the rectangle;

a – the length of the rectangle;

b – the width of the rectangle, respectively.

Due to the fact that we need to find the sum of the lengths of the sides of the rectangle, we can express this sum from the perimeter formula:

a + b = P / 2 = 188/2 = 94 cm.
