Answer 2

Answer:

The cost of laminating the tabletop if the dimensions are 9 dm 6 cm by 6 dm 5 cm at Rs. 50 per square meter = Rs. 31.20 = 31 Rupees 20 Paise

Step-by-step explanation:

Given that,

Length of the table = 9 dm 6 cm

Breadth of the table = 6 dm 5 cm

where dm is Decimeter

cm is centimeter

We have to convert these dimensions into meters.

To convert length into meters:

As we know,

1 dm = 10 cm

So, 9 dm = 9×10 cm = 90 cm

Length of the table = 90 cm + 6 cm = 96 cm

Now, we convert cm to m (meter).

1 cm = 0.01 m

So, 96 cm = 96×0.01 = 0.96 m

Length of the table = 0.96 m

To convert breadth into meters:

1 dm = 10 cm

So, 6 dm = 6×10 cm = 60 cm

Breadth of the table = 60 cm + 5 cm = 65 cm

Now, we convert cm to m (meter).

1 cm = 0.01 m

So, 65 cm = 65×0.01 = 0.65 m

Breadth of the table = 0.65 m

We know that as length and breadth are different, the table is a rectangle.

Area of a rectangle = Length of the rectangle × Breadth of the rectangle

So,

Area of the table = Length of the table × Breadth of the table

= 0.96 m × 0.65 m

= 0.624 $m^{2}$

Cost of laminating the tabletop per square meter = Rs. 50

Cost of laminating the tabletop per 0.624 $m^{2}$ = 50 × 0.624

                                                                      = Rs. 31.20

                                                                      = 31 Rupees 20 Paise

Therefore, the cost of laminating the tabletop if the dimensions are 9 dm 6 cm by 6 dm 5 cm at Rs. 50 per square meter = Rs. 31.20 =  31 Rupees 20 paise.
