Question

A door of length 2m and breadth 3.6mtr find the cost of white washing the wall, if the rate of white washing the wall is rupees 20 per meter square

Answer 1

length of door = 2m
breadth of door = 3.6 m

So area of door = 2 * 3.6
= 7.2 m ^2

So rate of white washing the wall = Rs 20 m ^2

So total cost of white washing the wall

=> 20 x 7.2
=> Rs 14.4 m. ^2

So cost of white washing the wall is Rs 14.4 m^2


hope this helps you
