Question

A fencing is required around a field 80 feet x 500 feet. if the fence posts have to be put a 20 feet intervals, how many posts will be required:

Answer 1

Sum of all sides =80+500+80+500 = 1160
then divide all sides by 20 as interval
so : 1160/20 = 58

Answer 2

Answer:

Step-by-step explanation:

80+80=160

500+500=1000

160+1000=1160

1160is the perimeter (Distance all round)

To get the number of posts formulae is :perimeter (distance)÷intervals

1160/20=58so 58 posts will be required.
