Q10) Each side of a square plot of land is 55 m. Find the cost of fencing the plot at the rate of Rs. 32 per metre.

Solution 10:

∵ Perimeter of square field = 4 x its side = 4 x 55 m

∴ Length of required fencing = 220 m Now, the cost of fencing = its length x its rate

= 220 m x Rs. 32 per metre

= Rs. 7040
