Question

Find the cost of fencing of a square park whose side is 105 m at the rate of Rs. 16 per meter.

Answer 1

Answer:

Rs.6720

Step-by-step explanation:

Perimeter of square park

= 4× side

=4×105

=420 m

Cost of fencing

= 420×16

= Rs.6720

Answer 2

${ \bf{ \underline { \underline{Given}}}}$

• Side $: \implies$ 105m
• Rate of per meter $: \implies$ ₹16m

${ \bf{ \underline { \underline{To \ find}}}}$

• To find the Perimeter of the squre park and rate of the perimeter per meter.

${ \bf{ \underline { \underline{Solution}}}}$

${ \underline{ \underline { \boxed{ \bf{Understanding \: the \: question}}}}}$

To find the Perimeter of square we have to use the formula after using the formula we will get the Perimeter of the square park Now, in the question it also has written to find the rate of the Perimeter and it also has given the rate of each meter So, to find the meter of Perimeter We just have to multiply the perimeter by the rate of each meter which is ₹16m.

$\underline{\bf\purple{\dag}\: {\pink{\mathfrak{As \ we \ that\: :}}}}$

$\;\boxed{\sf{\blue{Perimeter_{\:(square)} = 4 \times side}}}$

⠀⠀⠀$: \implies$ 105m × 4

⠀⠀⠀$: \implies$ ${ \boxed{ \underline{\underline{\mathfrak{\pink{p \leadsto 420m}}}}}}$

Now, we have to find the rate of fencing square park

⠀⠀⠀$: \implies$ ₹16 × 420m

⠀⠀⠀$: \implies$ ${ \boxed{ \underline{\underline{\mathfrak{\purple{Rate \leadsto ₹6,720}}}}}}$

•°• Hence, verified! that the Perimeter of square is 420 meter and rate of the Perimeter is ₹6,720
