Answer 2

To solve this problem, we need to find out how many rectangles with sides measuring 3 centimeters and 5 centimeters can be cut from a colored paper sheet that is 15 centimeters long and 9 centimeters wide.

Calculating the number of rectangles:

To find the number of rectangles that can be cut, we need to divide the length and width of the paper sheet by the length and width of each rectangle, respectively.

The length of the paper sheet is 15 centimeters, and the width is 9 centimeters. The length of each rectangle is 3 centimeters, and the width is 5 centimeters.

To calculate the number of rectangles that can be cut from the paper sheet, we divide the length and width of the paper sheet by the length and width of each rectangle, respectively:

Number of rectangles = (Length of paper sheet / Length of each rectangle) * (Width of paper sheet / Width of each rectangle)

Number of rectangles = (15 cm / 3 cm) * (9 cm / 5 cm)

Simplifying the equation:

Number of rectangles = 5 * 1.8

Number of rectangles = 9

Answer:

Anora will be able to cut 9 rectangles with sides measuring 3 centimeters and 5 centimeters from the colored paper sheet that is 15 centimeters long and 9 centimeters wide.
