Answer:
Step-by-step explanation:
here's ur answer...
length of the room=12.5m
breadth=9m
height=7m
we have to find it's CSA because we have to find the cost of painting walls.
CSA=2h(l+b)
=2×7(12.5+9)
=14×21.5
=301m²
area of both doors=2(l×b)
=2(2.4×1.5)
=2×3.6
=7.2m²
area of three doors=3(l×b)
=3(1.4×1.2)
=3×1.68
=5.04m²
area of wall without any doors and windows=
301-(7.2+5.04)
=301-12.24
=288.76m²
total cost=288.76×3.5
=₹1010.66
hope this helps....
