Q:
A) 56m | B) 65m |
C) 34m | D) 36m |
Answer: A) 56m
Explanation:
Explanation:
Length of the wire fencing = perimeter = 2(90 + 50) = 280 metres
Two poles will be kept 5 metres apart. Also remember that the poles will be placed along the perimeter of the rectangular plot, not in a single straight line which is very important.
Hence number of poles required = 280 / 5 = 56
