Ans. Before attempting this question, it is advisable to draw a rough sketch from the information provided. This helps in presenting a clear picture to us & prevents from making further mistakes.

You will notice that when you re-read the question, you can note down the main points like…….

Land size – 15’-6” X 9’-6”
Door Size – 3’-0” X 7’-0”
Window Size – 3’-0” X 4’-0” (2Nos.)
Wall Thickness – 9”
Room Height – 10’-0”

Lets make a rough diagram with the help of above measurements. We'll make the piece of land measuring fifteen feet six inches in length & nine feet six inches, in breadth.

 

 
 

 

Add nine inch wall on all four sides. This will reduce the internal area to fourteen feet by 8 feet. This is also the area of ceiling.

Add the door & two windows.

 

 
 

Lets mark the four walls as Wall A,B,C & D

 

 

 
 

Lets calculate the area required for painting:

Ceiling Area – 14’-0” X 8’-0”
                      = 112 sq ft.

Wall A – (14’-0” X 10’-0”) – (7’-0” X 3’-0”)
            = 140 -21
            = 119 sq ft.

Wall B – (8’-0” X 10’-0”) – ( 4’-0” X 3’-0”)
            = 80 – 12
            = 68 sq feet.

Wall D – Same as Wall B
                68 sq ft.

Wall C – 14’-0” X 10’-0”
            = 140 sq ft

 

 

 
 

Adding them all up, we get:

112 + 119 + 68 + 68 + 140

= 507 sq ft.

So, Mohan needs to paint 507 sq feet of internal room area.
