Question

The rate of fencing a rectangular garden of dimensions 400 cm x 100 cm is 310/m. How much money in ) is required to fence the garden?​

Answer 1

Answer:

The amount of money required to fence the garden is Rs. 3100.

Step-by-step-explanation:

We have given that,

For a rectangular garden,

Dimensions of garden = 400 cm * 100 cm

• Length = 400 cm = ( 400 ÷ 100 ) m = 4 m
• Breadth = 100 cm = ( 100 ÷ 100 ) m = 1 m

Rate of fencing = 310 Rs/m

We have to find the amount of money required to fence the garden.

Now, we know that,

Perimeter of rectanglular garden = 2 ( Length + Breadth )

⇒ Perimeter of rectanglular garden = 2 ( 4 + 1 )

⇒ Perimeter of rectanglular garden = 2 * 5

⇒ Perimeter of rectanglular garden = 10 m

Now,

Cost of fencing the garden = Perimeter of garden * Rate of fencing

⇒ Cost of fencing the garden = 10 m * 310 Rs/m

⇒ Cost of fencing the garden = 10 * 310 Rs * m ÷ m

⇒ Cost of fencing the garden = 3100 Rs

∴ The amount of money required to fence the garden is Rs. 3100.

Answer 2

Step-by-step explanation:

${\implies}{ \boxed{\mathbb{\red{given \: that}}}} \\ dimension \: (400 \times 100)cm \\ length = 400 cm\: \\ and \: breadth = 100cm \ \\{\implies}{ \boxed{\mathbb{\red{ to \: find = money \: required \: to \: fench \: garden}}}} \\ \\ {\implies}{ \boxed{\mathbb{\blue{explanation \: step \: by \: step}}}} \\ \\ \ firstly \: change \: it \: into \: meter \: (m) \: \\ therefore \: divided \: by \: 100 \: \\ we \: get \\ length \: = 4m \\ breadth = 1m \\ now \\ finding \: perimeter \: \\{\implies}{ \boxed{\mathbb{\pink{ using \: formula }}}}\\ \: {\implies}{ \boxed{\mathbb{\red{perimeter}}}} = 2(l + b) \\ = 2(4 + 1) \\ = 2 \times 5 \\ = 10 \\ {\implies}{ \boxed{\mathbb{\red{money \: required}}}} = { \boxed{\mathbb{\orange{rate \: \times perimeter }}}}\\ = 310 \times 10 \\ = {\implies}{ \boxed{\mathbb{\green{3100 \: rupees}}}}$
