Question

Shikha is making a birthday card and wants to put a border made of pink ribbon all the way around the front of the card. The card is a rectangle 7.4 m long and 4.4 m wide.

· How long will the pink border be?

· If she has to make 5 birthday cards, how much ribbon will be required?

Answer 1

Part 1⤵️

How long will the pink border be?

Given dimensions of the ribbon

• Length = 7.4 m
• Width = 4.4 m

`\boxed{ \rm \: perimeter = 2 * (length + \: breadth) }`

`\rm \: perimeter = 2 * (7.4 + 4.4)`

`\rm \: perimeter = 2 * 11.8`

`\rm \: perimeter = 23.6 m`

➪ The pink border will be 23.6 meter long...~

Part 2⤵️

If she has to make 5 birthday cards, how much ribbon will be required?

To find this, We need to multiply the length of 1 ribbon by the number of ribbons whose length we have to find..

• Length of 1 ribbon = 23.6

`\sf \to \: 5 \: ribbons = 23.6 * 5`

`\sf \\rightarrow \: 5 \: ribbons = 118 \: m`

➪ Therefore, She will require 118 meters lf ribbon to make 5 birtday cards...~
