Answer 2

Answer:

Given :-

• Anil cut a square paper with side 25 cm.
• He wants to put a tape on the border.

To Find :-

• How long will be the tape needed.
• What is the cost of the tape used if the price of the tape is Rs 3 per cm.

Formula Used :-

$\clubsuit$ Perimeter Of Square Formula :

$\bigstar \: \: \: \: \sf\boxed{\bold{\pink{Perimeter_{(Square)} =\: 4a}}}\: \: \: \: \bigstar$

where,

• a = Side

Solution :-

✰ First, we have to find the tape needed :

Given :

• Side = 25 cm

According to the question by using the formula we get,

$\implies \sf\bold{\purple{Perimeter_{(Square)} =\: 4a}}$

$\implies \sf Perimeter_{(Square)} =\: 4 \times 25\: cm$

$\implies \sf\bold{\red{Perimeter_{(Square)} =\: 100\: cm}}$

Hence, the required tap needed is 100 cm .

✰ Now, we have to find the cost of the tape used :

Given :

• Perimeter = 100 cm
• Rate of tape = Rs 3 per cm

According to the question :

$\implies \sf\bold{\purple{Cost_{(Tape)} =\: Perimeter_{(Square)} \times Rate_{(Tape)}}}$

$\implies \sf Cost_{(Tape)} =\: 100 \times 3$

$\implies \sf\bold{\red{Cost_{(Tape)} =\: Rs\: 300}}$

$\therefore$ The required tape needed is 100 cm and the cost of the tape used is Rs 300 .
