Question

The cost of grassing a square park is₹89,520.64 at the rate of₹2.56per m .find the perimeter of the park.​

Answer 1

Step-by-step explanation:

$\tt \: Area \: of \: field = \frac{Total \: cost}{Rate} \\ \tt \frac{89520.64}{2.56} = 34969 \: {m}^{2} \\ \tt \: Side \: of \: square \: field = \sqrt{Area} = \sqrt{34969 } = 187 \: m \\ \tt \: Perimeter = 4 \times side = 4 \times 187 = 748 \: m$

Answer 2

Step-by-step explanation:

$area \: of \: the \: field \: = \: \frac{total \: cost}{rate}$

$= \: \frac{89520.64}{2.56}$

$= \: 34969$

${side}^{2} = \: 34969$

$side \: = \: \sqrt{34969}$

$= \: 187$

$perimeter \: of \: field \: = \: 4 \times side$

$= \: 187 \times 4 \:$

= 748m Ans.
