Question

The total cost of whitewashing a wall at Rs. 12 per square meter is Rs. 2,688. If the length of the wall is Rs. 16 m. Find the breadth of the wall.​

Answer 1

Length= lm(let length be 'l')

Breadth=16m

Cost of white washing at the rate of 12 per meter =2688rs

Then area of the wall=2688*12/100=322.56m^2

Hence length=lxb

322.56=l×16=20.16m

Length=20.16m
