Answer 1

Answer:

Rs. 1200

hope this is the right answer.

Answer 2

Answer:

2400 RS

Step-by-step explanation:

COST FOR PAINTING= AREA OF WALL ×COST FOR 1M

WE ARE DOING ×COST FOR 1M BECAUSE AREA HAVING X METRES WILL REQUIRE THE MONEY THAT 1M=200 RS

SO, AREA OF WALL=L×B(AS ITS A RECTANGLE CAUSE SIDES ARE NOT SAME)

MEANS ,AREA= 4×3=12M^2

NOW,COST FOR PAINTING =12×200=2400RS

2400 RS IS REQUIRED TO PAINT WALL
