Question

The length of a rectangular Park is 620 metre and its breadth is 0.5 find the cost of fencing the park at the rate rupees 8 per metre
​

Answer 1

Given:

✻ Length of rectangular park = 620m

✻ Breadth of rectangular park = 0.5m

Find:

✺ Cost of fencing the park at the rate of ₹8/m

Solution:

➡ we, know that

⇒Perimeter of rectangle = 2(Length + Breadth)

where,

• Length = 620m
• Breadth = 0.5m

So,

⇒Perimeter of rectangle = 2(Length + Breadth)

⇒Perimeter of rectangle = 2(620 + 0.5)

⇒Perimeter of rectangle = 2(620.5)

⇒Perimeter of rectangle = 1241m

∴ Perimeter of rectangle = 1241m

Now,

⇢Cost of fencing 1m of park = ₹8

⇢Cost if fencing 1241m of park = 8×1241

= ₹9928

Hence, Cost of fencing the park = ₹9928

Answer 2

if length and.breadth of a rectangular park is 620m and 0.5km respectively then find perimeter and also find cost of fencing the park at the rate of 16per metre
