Question

a table cover 5 metre into 3 metre is applied on a meeting table if 25 cm of the table cover is hanging all around the table find the area of the table top

Answer 1

Length of table cover = 5m
Breath of table cover = 3m
As,
25 cm = 0.25 m table cover is handing all around , so
Length of table cover = [5-2(0.25)] m
                                  = 4.5 m
Breath of table cover = [3-2(0.25)] m
                                  = 2.5 m
Now,
Area of table top = (4.5 * 2.5) m2
                            = 11.25 m2
