Question

cost of ploughing in the square field is rupees 2450 @ rupees 2 per 100 square metres find the length of the side of the square​

Answer 1

Answer:

Step-by-step explanation:

Length of the side of the square = 350 meter

Step-by-step explanation:

Cost of ploughing in a square field = Rs. 2450

Rate at which the field is ploughed = Rs. 2 per 100 square meters

We need to find the side length of the square.

Now, Cost of ploughing = Area × Rate per 1 square meter

⇒ 2450 = Area × 2/100

⇒ Area = 2450 × 50

⇒ Area = 122500 square meters

Now, Area = Side²

⇒ side = √122500

⇒ Length of the side of the square = 350 meter
