Answer 1

Dimensions of the table cover,

Length = 4m

Breadth = 2m

If w =25cm = 0.25 m of the tablr cover is

hanging all around the table .

Dimensions of the table top,

Length = l = 4m - 2 × w

l = 4m - 2×0.25

l = 4m - 0.5 m

l = 3.5 m

Breadth = b = 2m - 2 × w

b = 2m - 2 × 0.25

b = 2 m - 0.5m

b = 1.5 m

Area of the table top = l × b

= 3.5 m × 1.5 m

= 5.25 m^2

According to the problem given,

Cost of polishinh the table top at rupees 25 per

squate meter.

Total cost of polishing the table top = 25 × 5.25
