The width of a rectangular flower bed is 3 meters. What is its length if the perimeter is 24m?

Since the flowerbed has a rectangular shape, therefore, when solving the problem, we will use the formula for a rectangle. The perimeter of a rectangle is the sum of the lengths of all its sides. According to the condition of the problem, the flower bed has a width of 3 meters, and its perimeter is 24 meters, which means we can find what the length of this flower bed is equal to.

24 = 3 + 3 + x + x.

24 – 6 = 2x;

2x = 18;

x = 18/2;

x = 9 meters.

Answer: The length of this flower bed is 9 meters.
