The perimeter of the rectangle is 150 dm. Its length is 150cm more than its width.

The perimeter of the rectangle is 150 dm. Its length is 150cm more than its width. Calculate the lengths of the sides of the rectangle.

Let the width of the rectangle be x cm, then its length is (x + 150) cm.The perimeter of the rectangle is 150 dm or 1500 cm.
The perimeter of a rectangle is calculated by the formula the sum of its length and width, multiplied by two:
2 * (x + x + 150) = 1500.
(x + x + 150) = 1500: 2.
2x + 150 = 750.
2x = 750-150.
2x = 600.
x = 600: 2.
x = 300.
We took the width of the rectangle as x, calculate its length:
300 cm + 150 cm = 450 cm rectangle length.
Answer: the width of the rectangle is 300 centimeters, the length of the rectangle is 450 centimeters.
