Question

A rectangular glass sheet is 6m long and 5m 20cm wide.

If glass sheet is available at the rate of Rs.150 per sq m,find the cost of glass sheet?​

Answer 1

Answer:

• The cost of glass sheet is Rs 4680.

Step-by-step explanation:

Given that:

• A rectangular glass sheet is 6 m long and 5 m 20 cm wide.
• Glass sheet is available at the rate of Rs. 150 per square m.

Converting the Breadth in m:

• 100 cm = 1 m
• 1 cm = 0.01 m
• 5 m 20 cm = 5 m + (20 × 0.01) m = 5 m + 0.2 m
• 5 m 20 cm = 5.2 m

Now we have,

• Length = 6 m
• Breadth = 5.2 m

To Find:

• The cost of glass sheet.

First finding the area of rectangular glass sheet:

Formula: Area of rectangle = (Length × Breadth)

• Area of rectangular glass sheet = (6 m × 5.2 m)
• Area of rectangular glass sheet = 31.2 m²

Now finding the cost of glass sheet:

• 1 m² glass sheet cost = Rs 150
• 31.2 m² glass sheet cost = Rs (150 × 31.2)
• 31.2 m² glass sheet cost = Rs 4680

Answer 2

Given

• Length of rectangular glass sheet = 6 m
• Breadth of rectangular glass sheet = 5 m 20 cm
• Cost of glass sheet per m² = Rs 150

To find

• Cost of glass sheet

Solution

• Length = 6 m
• Breadth = 5 m 20 cm
• Breadth = 5 m + 20(0.01)
• Breadth = 5 m + 0.2
• Breadth = 5.2 m

∵ 1 m = 100 cm

• Area = Length × Breadth
• Area = 6 × 5.2
• Area = 31.2

Hence, the area of rectangular glass sheet is 31.2 cm²

Now :-

• 1 m² = Rs 150
• 31.2 m² = ?
• 31.2 m² = 150 × 31.2
• 31.2 m² = 4680

Hence, the cost of the glass sheet is Rs 4680 /-
