A rectangle has an area of 45 square centimeters and a length of 10 centimeters.

What is the width of the rectangle?

55 centimeters

35 centimeters

4.5 centimeters

3.5 centimeters (my answer)

How can 45/10 = 3.5 ??

45/10 = 4.5

To find the width of a rectangle, you can use the formula for the area of a rectangle: area = length × width. In this case, you know that the area is 45 square centimeters and the length is 10 centimeters. To find the width, you can rearrange the formula to solve for width: width = area ÷ length.

Plugging in the given values, you get: width = 45 ÷ 10 = 4.5 centimeters.

Therefore, the correct answer is 4.5 centimeters.
