Answer 2

area of wall to colour is 14.2 m²

Step-by-step explanation:

given data

dimension of wall ab = 4.5 m × 3.6 m

dimension of door xy = 2 m × 1 m

to find out

exact area of wall for colour

solution

we know that colour will be done only on wall not on open area

so we get here effective area that is

area for wall colour = area of wall - area of door

so  area of wall = ( 4.5 × 3.6 ) =  16.2 m²  

and area of  door = ( 2 × 1 ) = 2 m²  

so

area of wall to colour = ab - xy  ...................1

area of wall to colour =  16.2 m² - 2 m²

area of wall to colour = 14.2 m²
