(A)Total area around the house= l*b
lenght=5m breadth=6m
total area=30m²
Dimensions of door and 3 windows=(2*1)+(2*1.5)+(2*1.5)+(1*1.5)
=9.5m²
Area to be painted=(total area)-(area od 1 door and three windows)
=30-9.5m²
=20.5m²
Money for 1 m²=0.5 Rs
money for 20.5 m²=20.5m²*0.5
=10.25Rs
10.area of the sheet=15*20cm²=300cm²
area used for making the box=4(4*3)+2(3*3)
=48+18===>66cm²
hence area of sheet wasted =300cm²-66cm²
=234cm²
hope the answer helped....comment below if doubt persists
