White washing of the wall has to be white washed excluding the area of door.
\red {=》} =》 Area of the wall including door = length × breadth
\red {=》} =》 4.5 m. × 3.6 m. = 16.2 m²
\red {=》} =》 Area of rectangular door = length × breadth
\red {=》} =》 2m. × 1m. = 2 m²
\huge{\underline{\underline{Now,}}}
Now,
Area of wall excluding door = Area of wall including door - Area of rectangular door
\red {=》} =》 16.2 m² - 2 m²
\red {=》} =》 14.2 m²
\huge {\underline {\underline {Given,}}}
Given,
The rate of white washing of 1 m² the wall = 20
The rate of white washing 14.2 m² the wall = 20 × 14.2
\red {===》} ===》 284
