A rectangular field is 450m length and 250m broad. Find the coast of putting a fence around it a rate of 50 paise per meter​

Answer 1

$\huge{\purple{\underline{\underline{\bf{\pink{Solution:-}}}}}}$

$\bullet\;\;\underline{\textbf{\textsf{AnswEr:-}}}$

• Cost of putting a fence around it at a rate of 50 paise per metre = Rs. 700

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\bullet\;\;\underline{\textbf{\textsf{Given:-}}}$

• A rectangular field is 450m length and 250m broad.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\bullet\;\;\underline{\textbf{\textsf{Need To Find :-}}}$

• Cost of putting a fence around it at a rate of 50 paise per metre = ?

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\:\:\:\:\;\:\;\footnotesize\bold{\underline{\underline{\sf{\red{Step\:by\:step\: Explanation:-}}}}}$

$\bullet\;\;\underline{\textbf{\textsf{Formula used here:-}}}$

${\underline{\boxed{\sf{Perimeter = 2 \times (length + breadth)}}}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\longrightarrow \sf {Perimeter = 2 \times (450 + 250)}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\longrightarrow \sf {Perimeter = 2 \times 700}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\longrightarrow \sf {Perimeter = 1400}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\bullet\;\;\underline{\textbf{\textsf{Hence:-}}}$

• The perimeter of Field = 1400 cm

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

Now, Cost of putting a fence around it at a rate of 50 paise per metre:-

$\longrightarrow \sf {\dfrac{1400 \times 50}{100}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\longrightarrow \sf {14 \times 5}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\longrightarrow \sf {700}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\bullet\;\;\underline{\textbf{\textsf{Therefore:-}}}$

• Cost of putting a fence around it at a rate of 50 paise per metre is Rs. 700.

Answer 2

Answer :

➥ The Cost of fencing the field at the Rate of 50 p = Rs.700

Given :

➤ Length of a rectangular field = 450 m

➤ Breadth of a rectangular field = 250 m

To Find :

➤ Cost of fencing the field at the Rate of 50 p = ?

Required Solution :

To find the Cost of fencing the field at the Rate of 50 p, first we need to find Perimeter of rectangular field, after that we will find the Cost of fencing the field at the Rate of 50 p, but our Answer come in paise so, We have to divide the money by 100 to get it in rupees. Then our answer will come in Rupees.

So let's start our Solution...

We can find Perimeter of rectangular field by using the formula of Perimeter of rectangular which says :

★ Perimeter = 2(l + b) ★

Here,

• I is the Length of rectangular field in m.
• b is the Breadth of rectangular field in m.

✎ So, let's find Perimeter !

⇒ Perimeter = 2(l + b)

⇒ Perimeter = 2(450 + 250)

⇒ Perimeter = 2 × 700

⇒ Perimeter = 1400 cm

Now we have Perimeter of rectangular field and and cost of putting a fence around it.

• Perimeter of rectangular field = 50 cm.
• Cost of putting fence around it = 50 Paisa per metre$.$

✎ So let's find Cost of fencing the field at the Rate of 50 p !

⇛ Cost of fencing the field = 1400 × 50

⇛ Cost of fencing the field = 70000 Paise

Converting Paise into Rupees :

⇛ Cost of fencing the field = 70000/100

⇛ Cost of fencing the field = Rs. 700

║Hence, the Cost of fencing the field at the Rate of 50 p is Rs. 700.║
