Question

the cost of levelling a square lawn at rupees 15 per square metre is rupees 19,935 .find the cost of fencing the lawn at rupees 22 per metre. ​

Answer 1

Answer:

3256.

Step-by-step explanation:

rate of leveling the square lawn = 15/m²

total cost = 19935

area of the square lawn = total cost/ rate of leveling

                                         = 19935/15

                                          = 1329 m².

sides of the square lawn = √1329.

                                          = 37 m.

perimeter of the lawn = 4*37

                                      = 148 m.

rate of fencing the lawn = 22/m

cost of fencing the lawn = 148*22

                                         = 3256.
