Question

a table cover of dimensions 3m 25cm * 2m 30cm is spread on a table if 30 cm of the table cover is hanging all around the table then find out the area of table cover which is lying outside the top of the table​

Answer 1

have to find out its area,

Given,

Length of cover =3m25cm=3.25m

Breadth of cover =2m30cm=2.30m

Now, area of the table cover =3.25×2.30=7.475m

2

Give, 30cm width of cloth is outside the table an each side.

Hence,

length of table =3.25−2×0.30=3.25−0.6=2.65m

Breadth of table =2.30−2×0.30=2.30−0.6=1.70m

Now, area of the top of the table

=2.65×1.70m=4.505m

2

So, Area of hanging cover of table = Area of cover of table - area of the top of the table

=7.475−4.505=2.97m

2

It has been given that Rs. 16 per square meter is the cost of polishing the table.

So, cost of polishing top of table =16 x area of top of table

=16×4.505=Rs.72.08

So, Rs.72.08 will be needed to polish the top of table.
