Answer:
Perimeter = 2(100+80)
= 2×180
= 360 m
No. of posts required = 360÷5 = 72
Length = 72×2 = 144m

Answer:
144 meter
Step-by-step explanation:
For the garden (rectangle)
breadth = 80 m
length = 100 m
Perimeter
= 2(length + breadth) m
= 2(100 + 80) m
= 2(180) m
= 360 m
Given,
A post is made after every 5 meter to hold the wire.
No of posts
= perimeter/5
= 360/5
= 72
Total length of the pipe for the posts
= No of post x length of each post
= (72 x 2) m
= 144 m
