Question

In order to fence a garden 70m long and 50m wide, metal posts are to be fixed every 5m apart. Each post is 3m long. What is the total length of the pipe required for the posts?

Answer 1

Answer :-

Length of the pipe required = 144 m.

Explanation :-

Given :

• Length of Garden = 70m.
• Breadth of Garden = 50m.

To Find :

• Total length of pipe required for the posts.

Solution :

The garden is to be fenced. So, We will find the Perimeter of the garden.

Perimeter = 2(l + b).

➝ Perimeter = 2(70 + 50).

➝ Perimeter = 2(120).

➝ Perimeter = 240m.

It is Given that,

Metal posts are to be fixed every 5m apart.

So,

➝ No. of Posts = 240/5.

➝ No. of Posts = 48.

In the Question, It is also Given that,

Each Post is 3 m long.

So,

➝ 48 × 3.

➝ 144m.

∴ Total length of the pipe required for the posts = 144 m.
