Quizplus · Accepted Answer

The formula for the area of a rectangle is A = L x W, where A is the area, L is the length, and W is the width. We are given that A = 18 cm^2 and L = 6 cm. Plugging these values into the formula, we get: 18 cm^2 = 6 cm x W. Solving for W, we can divide both sides by 6 cm: W = 3 cm. Therefore, the width of the rectangle is 3 centimeters, which corresponds to choice A. Let's use the formula for the area of a rectangle:
Area = length x width

We know that the area is 18 square centimeters and the length is 6 centimeters. Let's substitute those values in:
18 = 6 x width

To solve for the width, we can divide both sides by 6:
3 = width

Therefore, the width of the rectangle is 3 centimeters.
