Question

Cost of ploughing in a square field rs 2450 rate rs 2 per 100 sq m find the length

Answer 1

rs 2 is the cost in square field on area = 100 sq m

rs1 is the cost. in square field on area = 100/2 sq m

rs 2450 is the cost..............area= (100/2)*2450 = 1225*100= 122500 sq m

area of square field is 122500 sq m

and

we know that area of square is length square

so

length square = 122500sq m

length = √122500 = 350m
