Question

The area of a square ground is 6084 sq. m.
It is fenced at the rate of 40 per/m and
ploughed at the rate of 20/sq m. Find the
total cost.​

Answer 1

Answer:

Total cost will be ₹ 1,34,160.0

Step-by-step explanation:

Area = 6084

a^2 = 6084

a = 78 (under root of 6084 = 78)

Cost of fencing = Perimeter × 40

Perimeter = 4a = 78 × 4 = 312

Cost = 312 × 40 = 12480

Cost of ploughing = Area × 20

Area = 6084

6084 × 20 = 121680

Total cost = Cost of ploughing + Cost of fencing

Total cost = 121680 + 12480 = ₹1,34,160

Answer 2

Step-by-step explanation:

area = 6084

side×side=6084

side=square root of 6084= 78

perimeter=4×side=4×78=312m.

cost per meter for fencing=40

total cost for fencing=312×40=12480

cost per sq.m for ploughing=20

total cost for ploughing=6084×20=121680

total cost for both works=12480+121680

=134260

hence the answer.
