The length and width of the rectangle together are 20 cm. What is the length and width of the rectangle if the length is 4 times its width?
Let’s denote the width of the rectangle by variable x. The length of the rectangle is 4 times its width, which is 4x. Let’s compose and solve the equation, taking into account that the length and width of the rectangle together are 20 cm.
x + 4x = 20.
5x = 20.
x = 20/5 = 4 cm (rectangle width).
Rectangle length: 4x = 4 * 4 = 16 cm.
Answer: The length of the rectangle is 16 cm, the width of the rectangle is 4 cm.
