The perimeter of the rectangle is 72 cm. What is the length and width of the rectangle if the width is 3 times less than its length

Let’s make an equation.
X is the width of the rectangle; 3 * X is the length of the rectangle.
x + 3x + x + 3x = 72;
8x = 72;
X = 9.
3x = 3 * 9 = 27.
Answer: the width of the rectangle is 9 cm, the length is 27 cm.
Designated for x width ,. The length is 3 times more, so you need to multiply the width by 3. The rectangle has 4 sides: 2 widths and 2 lengths, add them and find the unknown value of x in the equation.
