2.5 mx 0.5 m and two windows of dimensions 1.5 m x 100 cm. The dimensions of the wall are 12 m x 6.5 m. Find the area of the wall to be painted​

Answer 1

Step-by-step explanation:

Area of door=2.5×0.5=1.25 m^2

Area of two windows= 2×1.5×1=3 m^2

Area of wall=12×6.5=78 m^2

Remaining Area=78-(1.25+3)=73.75 m^2
