Question

The length and breadth of a rectangular plot of land is 65.5 m and 32.5 m. what is the cost of the plot at the rate of rs 750 per square meter
​

Answer 1

Area of Rectangular Plot = Length × Breadth

⇒ Area of Rectangular Plot = 65.5 m × 32.5 m

⇒ Area of Rectangular Plot = 65.5 × 32.5 m²

⇒ Area of Rectangular Plot = 2128.75 m²

Cost of the Plot = ₹ 750 × 2128.75

⇒ Cost of the Plot = ₹ 1596562.5

Answer 2

Given:

• Length = 65.5 m
• Breadth = 32.5 m
• Cost = Rupees 75 / square meter.

Need to find:

• The total cost =?

Solution:

Area of the plot:

= length × breadth

= 65.5 × 32.5

= 2,128.75

The cost will be:

= Area × charge per square metre

= 2,128.75 × 750 Rupees

= 1,596,562.5 Rupees

Knowledge cell:

• Area of square = side × side

• Area of rectangle = length × breadth

• Perimeter of square = 4 × sides

• Perimeter of rectangle = 2×( length + breadth)
