Respuesta :

Part 1⤵️

How long will the pink border be?

Given dimensions of the ribbon

  • Length = 7.4 m
  • Width = 4.4 m

[tex] \boxed{ \rm \: perimeter = 2 \times (length + \: breadth) }[/tex]

[tex] \rm \: perimeter = 2 \times (7.4 + 4.4)[/tex]

[tex] \rm \: perimeter = 2 \times 11.8[/tex]

[tex] \rm \: perimeter = 23.6 m[/tex]

➪ 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

[tex] \sf \to \: 5 \: ribbons = 23.6 \times 5[/tex]

[tex] \sf \nrightarrow \: 5 \: ribbons = 118 \: m[/tex]

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