Answer 1

12) Given,

l=25 m

b=20 m

h=2 m

Area of floor=25*20

=500 m^2

Area of four walls=2*2(25+20)

=4*45

=180 m^2

Area of floor and four walls=680 m^2

Cost per 1 m^2=Rs. 20

Cost per 680 m^2=680*20

=Rs. 13600

Cost of cementing the floor and four walls is Rs. 13600.

13) Given,

h=6 m

Perimeter=300 m

Perimeter=2(l+b)

Area of four walls=2*h(l+b)

=Perimeter*h

=300*6

=1800 m^2

Cost per m^2=Rs. 60

Cost of painting the four walls=1800*60

=Rs. 108000
