The length of the rectangle is three times the width, and the sum of the lengths of all the sides of the rectangle is 64 cm.

The length of the rectangle is three times the width, and the sum of the lengths of all the sides of the rectangle is 64 cm. Find the length and width of the rectangle.

Find the sum of the length and width of the rectangle.
Since the opposite sides of the rectangle are equal to each other, for this we divide 64 centimeters by 2.
Will be:
64/2 = 32 cm.
Let’s denote the width of the rectangle as x.
Since the length is 3 times greater, its value will be: 3 * x cm.
Let’s make the equation:
x + 3 * x = 32.
4 * x = 32.
x = 32/4 = 8 centimeters (width).
3 * x = 3 * 8 = 24 cm (length).
Answer: The length of the rectangle is 24 cm, the width of the rectangle is 8 cm.
