Question

Arvind needs to lay 2 m long iron pipes vertically to fix fence wires in a garden 70 m long and 50 m wide. If he laid the iron pipes 5 m apart, find the total length of the iron pipe bought.​

Answer 1

Answer :

Given, Length of the garden =70 m

Breadth of the garden =50 m

Perimeter of the garden =2×(Length+Breadth)

=2×(70+50)

=2×120=240 m

On the perimeter of the garden, it is given that Arvind fixed a post every 5 meters apart.

So, the number of posts required =

5

240

=48

Given Length of each is 2 m.

Therefore, Total length of the pipe required =48×2=96 m
