SOLUTION

THE GIVEN LENGTH OF ROOM=5METRE

THE GIVEN BREADTH OF ROOM=4 METRE

THE GIVEN HIGHT OF ROOM=3METRE

MEAN IT CAN BE OBSERVED THAT 4 WALLS AND THE CELLING OF THE ROOM ARE TO BE WHITE WASHED = AREA OF WALL+CELLING OF ROOM

=2LB+2BH+LB

=[2×5×3+2×1×3+5×4]

it can be observed that 4 walls the celling of the room are to be white washed

total white washed area =area of collingof room

=2LB +2BH+LB

={2×5×3+2×4×3+5×4}

=30+24+20

AREA =74 MERER SQUARE

COST OF WHITE WASHING PER METRE square

= rupee 7.50

cost of white wash per meter ×the total area of wall

74×7.50= RUPEE 555
