Question

Find the length of marking tape
required to use around switch
boards of dimensions e inches by
3 inches​

Answer 1

Step-by-step explanation:

Given,

Dimensions of each switchboard 8 inches by 3 inches.

There are 6 such switchboards.

To find,

Length of tape required to use around them.

Solution :

Firstly finding perimeter of each switchboard :

⇒ Perimeter = 2(l + b)

⇒ Perimeter of each switchboard = 2(8 + 3)

⇒ Perimeter of each switchboard = 2 * 11

⇒ Perimeter of each switchboard = 22 inches.

Now there are 6 such switchboards.

And, length of tap required = Perimeter of 6 switchboards.

⇒ Length of tap required = 22 * 6

⇒ Length of tap required = 132 inches.

Therefore,

Length of tap required to use around them = 132 inches.
