Question

A rectangle garden of dimensions 36m 30m needs to be fenud. Find the length of fencing required? What will be the cost of fencing at Rs100 per meter.

Answer 1

Answer:

★ Total cost = Rs 13200 ★

Step-by-step explanation:

Given:

• Length and Breadth of rectangular garden is 36 m and 30 m respectively.
• Cost of fencing is Rs 100/m

To Find:

• Cost of fencing of whole rectangular garden .

Solution: We know that Perimeter of rectangle-

★ 2 ( Length + Breadth ) ★

• Putting the values in formula •

$\small\implies{\sf }$ 2 ( 36 + 30 )

$\small\implies{\sf }$ 2 x 66

$\small\implies{\sf }$ 132 m

★ Cost of fencing per metre = Rs 100 ★

∴ Cost of fencing for 132 m = Rs (132 x 100)

$\small\implies{\sf }$ Cost of fencing = Rs 13200

Hence, Cost of fencing whole rectangular garden is Rs 13200

Answer 2

Answer:

Given:-

• Length of the garden = 36 m
• Breadth of the garden = 30 m
• Shape of the garden : $\boxed{Rectangular}$

Perimeter of the garden:-

2[(Length) + (Breadth)] units

(Formula for finding perimeter of the garden or any Rectangular object)

= 2(36 + 30) m

(Put the values of Length and Breadth)

= 2(66) m

(Added 36 with 30)

= 132 m

(Perimeter of the garden)

NOW,

Finding the cost of fencing:-

Rate of fencing = Rs 100/m

Therefore, total cost :-

Rs 100 × 132m

(We have set an expression to take out the output/cost)

= Rs 13200

(Total cost of fencing)

REQUIRED ANSWER:-

Therefore, total cost of fencing is Rs. 13200.

TheAssassin's BRAIN BOOSTER:-

Know more about a rectangle:-

Area of Rectangle = (Length)(Breadth) unit².

In case of 3D objects,

Rectangle is known as Cuboid.

Hence,

Volume becomes = (Length)(Breadth)(Height) unit³.
