Answer 2

Answer:

Area of white washing= 212 m²

Cost of white washing= ₹ 5300

Step-by-step explanation:

Area of the door= l*b =2*1.5= 3 m²

Area of  4 windows= l*b= 1*1.5*4=6 m²

Area of the room= 2h(l+b) = 2*6.5* (9+8)

=13*17= 221 m²

Area of white washing= 221 m²- 6 m²-  3 m²

=212 m²

Cost of white washing= 212 m²*₹25=  ₹ 5300
