surface of square ispaved with tile. the total expenditure at the rate rs 25 per meter is rs 176400. what is the lengthof eachside of the wall?

Answer 1

Rate = Rs. 25 per m²
total cost = Rs. 176400

total area = 176400 / 25 = 7056 m²
let the side of the square = a
area = a² = 7056 m²
⇒ a = √7056
⇒ a = 84m

Length of each side of the square wall is 84m.
