Answer:
TOTAL COST = Rs.593.25
Step-by-step explanation:
TOTAL AREA OF THE WALL = l×b
= 11×12
= 132 m sq.
AREA OF DOOR FRAME. = l×b
= 5×3
= 15 m sq.
AREA OF SQUARE WINDOW= a×a
= 2×2
= 4 m sq.
AREA OF WALL TO BE PAINTED = 132 - 15 - 4
= 113 m sq.
COST OF PAINTING 1m sq of wall= rs.5.25
COST OF PAINTING TOTAL WALL=113 × 5.25
=rs.593.25
