Question

One side of square garden Is 85 decameter what is the cost of fencing it at the rate of 25 paise per meter

Answer 1

The formula for the perimeter P of a square is: P = 4s, where s is the length of one of the 4 congruent sides of a square.

We're given that one side of a square garden is s = 85 decameters, but since 1 decameter = 10 meters; 85 decameters = 85 decameters(10 meters/decameter) = 85(10) meters = 850 meters. Therefore, the perimeter of the square garden is:

P = 4s

= 4(850 meters)

= 3400 meters

Therefore, the cost C of fencing this square garden at a rate of 35 paise per meter is:

C = (25 paise/meter)P

= (25 paise/meter)(3400 meters)

= (25)(3400) paise

C = 85,000 paise is the cost of fencing the square garden at the rate of 25 paise per meter.

or

C = 85,000 paise (0.0028 USD)/25 paise)

= [85,000(0.0028 USD)]/25

C = $9.52 is the cost of fencing the square garden at the rate of 0.0028 USD per meter.

I hope it help you
