Find the perimeter of the rectangle if a = 230cm, b = 12cm, the second side of the rectangle

Find the perimeter of the rectangle if a = 230cm, b = 12cm, the second side of the rectangle if the perimeter is 320m, and one of the sides is 122cm.

We find the perimeter of the rectangle by the formula: p = (a + b) * 2, where p is the perimeter, a is the length of the rectangle, b is the width of the rectangle.
1) Find what the perimeter of the rectangle is.
(230 + 12) * 2 = 242 * 2 = 484 centimeters.
2) Let’s calculate what is the second side of the rectangle.
(320 – 122 * 2) / 2 = (320 – 244) / 2 = 76/2 = 38 centimeters.
Answer: The perimeter of the rectangle is four hundred and eighty-four centimeters. The second side of the rectangle is thirty-eight centimeters long.
