Question

Ques.-10 The cost of plastering a square wall at the rate of 24Rs. Per sq. m. 3456Rs.
Find the length of each side of the wall​

Answer 1

Answer:

12

Step-by-step explanation:

Rate and cost of plastering a wall is given 24Rs. Per sq. metre and 3456Rs respectively

Cost of plastering = area of the wall*rate

area of the wall = cost of plastering/rate of plastering

Area of the wall= 3456/24

on dividing we get area of wall = 144 sq metre

as we know length*length=area of square

so length * length=144

length = √144

length = 12
