Answer 2

Step-by-step explanation:

GivEn:

⋆ Breadth of Rectanglular park = 50 m

⋆ Area of Rectanglular park = 4100 m²

Need to find:

⋆ Cost of fencing at the rate of ₹30 per metre

Solution:

✇ Let length of rectanglular field be l cm.

★ According to the given Question:

Area of Rectanglular park is 4100 m²

⇢ l × b = 4100

⇢ l × 50 = 4100

⇢ l = 4100/50

⇢ l = 82 m

∴ Length of rectangular park is 82 m.

⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Now, We need to find perimeter of field to find the cost of fencing.

Perimeter of Rectangle = 2(l + b)

⟹ 2(82 + 50)

⟹ 2 × 132

⟹ 264 m

Therefore,

Total cost of fencing at the rate of ₹30 per m

⟹ Perimeter × 30

⟹ 264 × 30

⟹ ₹ 7920

∴ Hence, cost of fencing rectanglular field at the rate of ₹30 per m is ₹7920.
