Question

The cost of ploughing in a square field is Rs 2450 at the rate of Rs 2 per 100sq meter . Find the lenght of side of the square?​

Answer 1

for rs 2 = 100sq .metre

rs 2450 = 2450 × 100 / 2 = 122500 sq.metre

thus the area = 122500m^2

Length of side of square = underoot of area = underroot of 122500 m^2 = 350 m

Thus the length of side of square is 350m
