Answer 2

${\tt{\underline{Given:-}}}$

There is a wall of height 9 ft and length 12 ft

Now, There is a window in the wall which is 2 ft by 4 ft

${\tt{\underline{Need\;To\;Find:-}}}$

The area required to be painted

${\tt{\underline{Answer:-}}}$

=> Area of the wall = Length × Height(Breadth)

=> Area of the wall = 12 × 9

=> Area of the wall = 108 sq. ft

=> Area of the window = Length × Height(Breadth)

=> Area of the window = 4 × 2

=> Area of the window = 8 sq. ft

=> Area to be painted = Area(Wall) - Area(Window)

=> Area to be painted = 108 - 8

=> Area to be painted = 100 sq. ft
