Question

A table cover 4m*2m spread on a table . find the cost of polishing the top of the table at rate 2.25per sq m if 25cm table cover is hanging all round the table​

Answer 1

Step-by-step explanation:

length of table cover = 4 m = 400 cm

breadth of table cover = 2 m = 200 cm

as it is hanging 2.5 cm on all sides of the table

length of table = 400 - 25 = 375 cm = 3.75 m

breadth of table = 200 - 25 = 175 cm = 1.75 m

area of table = l × b

= 3.75 × 1.75

= 6.5625 m

cost of polishing 2.25 per sq m

total cost for 6.5625 m

= 6.5625 × 2.25

= 14.76 approx
