Question

A door of length 4m and breadth 3m is fitted in a wall. The length of the wall is 16m and breadth of the wall is 13m 9cm. Find the cost of white washing the wall at the rate 23 per square metre

Answer 1

Your solution:
Given,
Length of Door= 4m & Breadth of Door= 3m
Therefore,
Area of Door= L×B = 4m×3m = 12m^2

Given,
Length of Wall= 16m & Breadth of Wall= 13.9m
Therefore,
Area of wall= L×B = 16m× 13.9m = 222.4 m^2

Area required for whitewashing
= Area of wall - Area of door
= (222.4 - 12) m^2
= 210.4 m^2

Cost for whitewashing per square metre
= 23 × Area required for whitewashing
= (23 × 210.4) rupess
= 4,839.2 rupees.
