Question

A door of length 2.5m and breadth 1.5m is fitted I in a wall. The length and breadth of the wall are 6m and 4.5m respectively. Find the cost of white washing the wall at the rate of RS 30 per sq m

Answer 1

first we will calculate area of door
area = l x b
= 2.5x1.5 = 3.75 m
now area of wall = 6 x 4.5 = 27
now we will subtract both area then
27 - 3.75 = 23.25
now cost of white washing = 23.25 x 30 = 697.5
