The area of the square field is 324 m square. If the cost of ploughing grass on it is Rs. 9 per m square and the cost of fixing fence is at the rate of rs. 7 per meter. then what will be the total cost of ploughing grass on the field and fixing fence all around the field?
Answer:
rs 3420
Step-by-step explanation:
area of a square= side^2
area of the field = 324m^2
side of the field is =
Side^2= 324
side=√324
side = 18 m
the cost of ploughing grass= Rs. 9 m^2
then the cost of ploughing= 9 x 324
= Rs 2916
perimeter of a square = 4 x Side
= 4 x 18
= 72 m
cost of fixing fence is at the rate= rs. 7 per meter
cost of fencing = 7 x 72
= rs 504
total cost = 2916+504= rs 3420
