Answer:

area of doors=l×b

=2.5×1.5(m square)

=3.75m square

area of 2 doors=2×(3.75m square)

=7.5m square

area of window=l×b

=1.5×1.8(m square)

=2.75m square

area of 2window=2(2.75m square)

=5.5m square

The cost of plastering 1m square =Rs.75

Total area of windows and door =(7.5+5.5)m square

=13m square

The cost of plastering 13m square =(13×75 )m square

=Rs.975 answer
