Question

The area of a square shapped paddy field is 10000 sq. m. then it's perimeter is -
i)40m.
ii)100m.
iii)200m .
iv)400m.​

Answer 1

Answer:

Given :-

• The area of a square shaped paddy field is 10000 m².

To Find :-

• What is the perimeter of a square shaped paddy field.

Formula Used :-

➲ Area of square = (a)²

where,

• a = Side of length of a square

➲ Perimeter of a square = 4(Side)

Solution :-

First, we have to find the side of length of a square shaped paddy field :

Given :

• Area = 10000 m²

Then, according to the question,

↦ (a)² = 10000

↦ a² = 10000

↦ a = √10000

➦ a = 100 m

Hence, the side of length of a square shaped paddy field is 100 m.

Now, we have to find the perimeter of a square shaped paddy field :

Given :

• Side = 100 m

According to the question by using the formula we get,

⇒ Perimeter = 4(100)

⇒ Perimeter = 4 ×100

➠ Perimeter = 400 m

∴ The perimeter of a square shaped paddy field is 400 m.

Hence, the correct options is option no iv) 400 m.

Answer 2

Answer:

The perimeter of a square-shaped paddy field is 400m.

Step-by-step explanation:

Step 1

Given

The area of a square-shaped paddy field is 10000 sq. m.

The area of the square is a² where a is the length of the square.

a²=10000 sq. m.

a=100 m.

Step 2

The perimeter of the square is (4a) i.e. 4×side.

Substitute the value of a in (4a).

4×100=400

Hence, the perimeter of a square-shaped paddy field is 400m.
