Question

The side faces of a ballot box is in the shape of a square. Its area is 65536 cm2

. Find the side

length of the ballot box.

Answer 1

Answer:

here!

Step-by-step explanation:

We have given that; Area of square field = 65536 m2

Area of the square is equal to = side× side

Let ‘a’ be the side of the square, then a×a=65536

a2=65536

a=65536−−−−−√

a=256 so, side of the square = 256 m

Now, we have to calculate the perimeter of the square. Perimeter of the square is the length of all the boundaries of the square. Since, there are 4 sides of square of equal length therefore ;

Perimeter of square = 4×side

Side of square = 256 m

So, perimeter of square =4×256=1024

Perimeter of square is 1024 m

Now we can calculate the cost of fencing the field. We have given that the cost of fencing of 1m is 5Rs.

So, cost of fencing the boundaries = perimeter × 5

=1024×5=5120

Therefore the total cost of fencing is 5120 Rs.

So, the correct answer is “5120 RS”.
