Question

Divya glued a ribbon around a clipboard. The clipboard is 9 inches wide and 11 inches tall. What is the length of ribbon used and the area of the clipboard?

Answer 1

Based on the dimensions of the clipboard, the length of the ribbon is 40 inches and the area of the clipboard is 99 inches ².

The ribbon goes around the clipboard which means that its length is the clipboard's perimeter which is calculated as:

= 2 x length + 2 x Width

= 2 x 9 + 2 x 11

= 18 + 22

= 40 inches

The area of the clipboard will be:

= Length x Width

= 9 x 11

= 99 inches ²

In conclusion, the length is 40 inches and the area is 99 inches²
