Answer:
[tex] 180 \, \textsf{cm} [/tex]
Step-by-step explanation:
To find the length of the ribbon required to paste around the square painting, w can use the perimeter formula for a square.
The perimeter ([tex]P[/tex]) of a square is given by the formula:
[tex] \Large \boxed{\boxed{P = 4 \times \textsf{side}}} [/tex]
In this case, the side of the square painting is [tex]45 \, \textsf{cm}[/tex]. Substitute this value into the formula:
[tex] P = 4 \times 45 [/tex]
[tex] P = 180 \, \textsf{cm} [/tex]
So, Nalin will need [tex]180 \, \textsf{cm}[/tex] of ribbon to paste around the square painting.
