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...~
