Question

Aroom has dimension 12 metre*10meter*8m*. There is one door of dimension 4m*2m and a window of dimension 2m*1m*. Find the area of four walls, which will be Whitewashed
​

Answer 1

AREA OF DOOR = l × b

= 4×2 = 8 m^2

AREA OF WINDOW = l × b

= 2 × 1 = 2 m^2

AREA OF WALL = 2 ( l + b ) h

= 2 ( 12 + 10 ) 8

= 2 ( 176 ) = 352 m ^2

AREA OF WALL WHICH WILL BE WHITEWASH

= AREA OF WALL – AREA OF DOOR + AREA

OF WINDOW

= 352 – 8 + 2

= 352 – 10

= 342 m ^2
