| July 6, 2021 | education
The problem can be solved using an equation.
Let’s say the width of the rectangle = x meters.
(4x + x) * 2 = 30.
5x * 2 = 30.
10x = 30.
X = 30: 10.
X = 3.
The width of the rectangle is 3 meters.
This means that the length of the rectangle is 3 * 4 = 12 meters.
Answer: The length of the rectangle is 12 meters.
