The length of the rectangle is 3 times its width, the difference in length and width is 6 cm. What is the length and width of the rectangle.
Let’s denote the width of the rectangle by x. Since the length of the rectangle is 3 times the width, the length is 3x.
The difference in length and width is 6 cm, we will compose and solve the equation:
3x – x = 6;
2x = 6;
x = 3.
According to the meaning of the introduced designations, the width of the rectangle is 3 cm, and the length is 3 * 3 = 9 cm.
