Question

Find the cost of fencing a square field of 10 acres at RS 4.80 per yard

Answer 1

Answer:

Rs. 4224.

Step-by-step explanation:

We know that 1 acre = 4840 yards

⇒                   10 acres = 4840 × 10

⇒                   10 acres = 48400 yards

That means the area of square field is of 48400 square yards

So, Let the length of one side of field is "a"

Area of square = a²

⇒ 48400 = a²

⇒ a = √48400

⇒ a = 220 yards

Now for the fencing of square field, we have to calculate its perimeter which is given by = 4×a

⇒                              4×220

⇒                              880 yards

Now, according to question Rs. 4.80 per yard

then, the total amount is = 4.80×880

                                         = Rs. 4224.
