Question

A rectangular park is of length 100 m and breadth 50 m. Find the cost of fencing the park at the rate of rupee 5 per meter. ​

Answer 1

Answer: ₹1500

Step-by-step explanation:

Length of park= 100m

Breadth of park= 50m

Perimeter of the park= 2(l+b)

=2(100+50)

=2×150=300m

So, cost of fencing the park= 300×5

= ₹1500

Hope it helps :)

Answer 2

Given:-

• Length of Rectangular Park = 100m
• Breadth of Rectangular Park = 50m
• Rate of fencing = Rs.5/m²

Find:-

• Cost of fencing the park.

Solution:-

we, know that

➢ Perimeter of Rectangle = 2(l + b)

where,

• Length, l = 100m
• Breadth, b = 50m

• Substituting these values •

➤ Perimeter of Rectangle = 2(l + b)

➤ Perimeter of Rectangle = 2(100 + 50)

➤ Perimeter of Rectangle = 2(150)

➤ Perimeter of Rectangle = 300m

So, Perimeter of Rectangle is 300m

Now,

ↁ Cost of fencing 1m = Rs.5

ↁ Cost of fencing 300m = 5 × 300 = Rs.1500

Hence, Cost of fencing the given Rectangular park is Rs.1500
