Surface of a square wall is paved with tiles. the total expenditure at the rate rs 25 per sq. m is rs.1 76 400.what is the length of each side of the wall?

Let the length of the side of the square wall = x meter

We know that area of the square , where x is the side of the wall

Given that rate of expenditure for 1 square meter of the wall = 25 rupees

Then total expenditure on meter of the wall

Given that total expenditure on the wall = 176400 rupees

Then both expressesions for the expenditure will be equal and we get equation:

take square root of both sides

x=84

Hence final answer is 84 meter.
