Question

) Find the area feild MNOP i
PN-20.8 m MA- 12.0 and Bo=16.8m.
Also find the cost
field at the date of Rs 45 per m




​

Answer 1

Answer:

Area=60025 m square =side^2

Therefore, side of field= 245m

Now, the perimeter or the length of boundary of field= 4*side= 980m

Now, we know that speed=distance/time

But given speed is in km/hr

So, speed in m/s= 18*(1000/3600) =18*(5/18) = 5m/s

Now, speed = distance/ time

So, 5= 980/t

So, time taken= 980/5= 196 seconds

or 3 minutes 16 seconds.
