The area of a rectangle is calculated with the formula A=lw. If the area of a rectangle is 52.5 m2 and the width is 5 m, what is the length? Explain the solution to the real-world problem.

The length is 262.5 m.
The length is 262.5 m.

The length is 10.5 m.
The length is 10.5 m.

l=10.5
l equals 10.5

The length is 262.5 m2

1 answer

The correct answer is 10.5 m.

To solve the problem, we can use the formula for calculating the area of a rectangle: A = l * w.

Given that the area is 52.5 m2 and the width is 5 m, we can substitute these values into the formula and solve for the length.

52.5 = l * 5

To solve for l, we divide both sides of the equation by 5:

52.5 / 5 = l

l = 10.5

Therefore, the length of the rectangle is 10.5 m.
