Question

the cost of laying grass is ₹2754 at the rate of ₹8.50 per square metre in a square lawn. find how much it would cost to erect a fence along its boundary at ₹11.50 per metre​

Answer 1

Answer:

₹ 828

Step-by-step explanation:

total cost = 2754 rs

rate per m² = 8.50 rs

area of lawn = 2754/8.50

                     = 324 m²

perimeter of lawn = √324

                              = 18 m

                              = 4*18

                              = 72 m

total cost = 11.5*72

               = ₹ 828
