Answer 1

Answer:

Area of room = 8m × 7m × 5m

= 280 m^2

Area of two Windows = (2 × 1 ) m^2

= 2 m^2 × 2

=4 m^2

Area of Doors = (3 ×1) m^2

= 3 m^2

cost of white washing = ( 280 - 4 - 3)m^2

= 273 m^2 × 50

= ₹ 13650

Answer 2

Answer:

formula used

• area of a cuboid=2(lb+bh+hl)
• volume=l×b×h

so here we will use areal formula....

total area of the bedroom is

=2(8*7+7*5+5*8)-2(2*1)-(3*1)

=262-2-3

=257 m^2

total cost=(257*50)Rs=12850 Rs
