Question

A table cover 4 m x 2 m is spread on a meeting table. If 25 cm of the table cover is hanging all around the table,
then find the cost of polishing the table top at * 2.25 per square metre.​

Answer 1

Step-by-step explanation:

length of table = length of table cover - 2(25/100)

= 4 - 1/2

= 3.5 m

breadth of table = breadth of table cover - 2(25/100)

= 2 - 1/2

= 1.5 m

area = 3.5 x 1.5

= 5.25 m²

cost = area x 2.25

= 5.25 x 2.25

= 11.1825
