Question

2. Manan made a plastic pouch for his electronic equipment that was
square in shape with a side of 15 cm. Find the length of the zipper
he needs if the zip has to cover only three sides.​

Answer 1

Answer:

45cm

Step-by-step explanation:

As it has asked to cover 3 sides of it with a zip

According to perimeter of square 4×side

here 3×side

= 3×15cm

= 45cm

Answer 2

Given,

A pouch of square shape with side = 15 cm.

To find,

Length of the zipper needed to cover just 3 sides of the pouch.

Solution,

The length or distance around a two-dimensional shape can be found simply by calculating its perimeter.

For a square, the perimeter is given by,

P = 4×(side of the square)

However, for the given pouch, we need a zipper to cover only 3 sides. So, the length of the zipper (L) can be found as follows.

L = 3×(side of the square pouch)

⇒ L = 3×15

⇒ L = 45 cm.

Therefore, for a square pouch of side 15 cm, the length of the zipper needed to cover 3 sides will be 45 cm.
