Question

A square field has the area 8.41 acres. Find the cost of
putting the fence around it at the rate of Rs. 8/m, (1 acre
= 100 m2)​

Answer 1

Answer:

928 rupees

Step-by-step explanation:

1 acre=100m2

8.41acre=841 m2

Now,

area of square= 841 m2

s*s=841

s2=841

s=29 m

Now,

perimeter of square= 4 *s

= 4 * 29

= 116m

Now,

rate of fencing= rs 8/ m

so

cost of fencing=8*116

=928 rupees

Answer 2

Concept:

Area of square is calculated by squaring its sides.

Given:

We are given that the area of square is 8.41 acres and the rate of fencing is Rs. 8 / m.

Find:

The cost of putting a fence around.

Solution:

Area of square field = 8.41 acres.

Side² = 8.41 acres = 841 m²

Side = 29 m

Rate of putting fence = 8 / m

Perimeter of square = 4 ( side )

P = 4 (29) m

P = 116 m.

Cost of putting fence = Rs. 116 × 8

Cost = Rs. 928

Therefore, the cost of putting a fence around is Rs. 928.
