The length and width of the rectangle together are 28 cm. What is the length and width of the rectangle if the length is 3 times its width?
Length and width are equal – 28.
Length – 3 times its width.
Determine the length and width of the rectangle. We write down the solution.
Let’s denote the width by x. Then the length is 3x. Next, we compose an expression.
3x + x = 28.
4x = 28.
X = 28: 4 = 7 cm.
This means the width is 7 centimeters.
Next, we define the length.
7 * 3 = 21 cm.
The length of the rectangle is 21 centimeters.
Answer: the length of the rectangle is 21 cm, the width is 7 cm.
