Question

7. A table cover 5 mx 3 m is spread on a table top. If 25 cm of the cover hanges all
around the table, then find the cost of polishing the table @ 1 per sq. cm.​

Answer 1

Answer:

5m=500cm

and 3m=300cm

so (500-50)cm=450cm, (300-50)cm=250cm

so the new length and breadth are 4.5m and 2.5m

area =l*b

=4.5m*2.5m

=1125m^2
