Question

:) Find the cost of mica used for the top of the table of size 195 cm X 85cm at the rate of 7.30Rs per
100cm square.​

Answer 1

Answer:

Rs 40.88

Step-by-step explanation:

Rate = 7.30 per 100 cm

        = 7.30 per 1 m            {100cm=1m}

Length of mica = 195cm = 1.95 m

Breadth of mica = 85cm = 0.85 m

 Total mica required = perimeter of the table-top

                 = 2(length + breadth)

                 = 2(1.95 + 0.85)

                 = 5.6 m

Cost = rate x perimeter

        = Rs 7.30 x 5.6

        = Rs 40.88

Answer 2

Answer:

Given :-

• Length of table = 195 cm = 1.95 m
• Breadth of table = 85 cm = 0.85 m
• Rate = 7.30 per 100 cm = 7.30 per m

To Find :-

Total cost

Solution :-

We know that

$\pink{ \mid \mid} \pmb{Perimeter = 2(l + b)} \pink{ \mid \mid}$

Perimeter = 2(1.95 + 0.85)

Perimeter = 2(2.8)

Perimeter = 5.6 m

Finding cost

Cost = Perimeter × Rate

Cost = 7.3 × 5.6

Cost = ₹40.88
