Question

Find the cost of fencing a rectangular field of length 200 m and breadth 150 m at ₹4 per metre.

Answer 1

Answer:

The Cost of Fencing the rectangular Garden is Rs.2800

Step-by-step explanation:

• Length = 200 m, Breadth = 150 m
• cost of Fencing = ₹4 per metre

$\succ$$\boxed{\sf{Perimeter}_{(Rectangle)} = \sf{2(l + b)}}$

2(200 + 150) = 700

Cost of Fencing = 700 x 4 = 2800

Hence, The Cost of Fencing the Rectangular Field is ₹2800.

Answer 2

Given :

• Length and Breadth of Rectangular field = 200 m and 150 m.
• Cost of Fencing = ₹4

To find :

• the cost of fencing the rectangular field.

Solution :

⇒ Let's find the Perimeter of the rectangular field.

$\sf \longrightarrow Perimeter = (length \times 2) +( breadth \times 2)$

Here,

• Length = 200 m
• Breadth = 150 m

-----------

$\sf \longrightarrow Perimeter = (length \times 2) +( breadth \times 2)$

$\sf \longrightarrow Perimeter = (200 \times 2) +(150 \times 2)$

$\sf \longrightarrow Perimeter = (400) +(300)$

$\sf \longrightarrow Perimeter = 700$

$\sf \therefore Perimeter = 700 \: m$

⇒ Let's find the cost of fencing.

$\longrightarrow \sf Cost = Perimeter \times Cost \: per \: metre$

$\longrightarrow \sf Cost = 700 \times 4$

$\longrightarrow \sf Cost = 2800$

$\therefore \sf Cost = 2800$

• Therefore, the cost of fencing the rectangular field is ₹2800.
