Question

1. The area of a square shapped paddy field is 10000 sq. m. then its perimeter
is
(a) 40 m (b) 100 m (c) 200 m (d) 400 m
​

Answer 1

Answer:

Option d) 400 m

The perimeter of the Square is 400 m.

Step-by-step explanation:

Given :

Area of the Square = 10000 m²

To find :

The perimeter

Solution :

Let the side be y

★ Area = Side × Side

⇒ 10000 = y × y

⇒ y² = 10000

⇒ y = $\sf{\sqrt{10000}}$

⇒ y = 100

Side = 100 m

$\rule{300}{1.5}$

★ Perimeter = Side × 4

⇒ 100 × 4

⇒ 400

Perimeter = 400 m

Therefore, the perimeter of the Square is 400 m.

Answer 2

AnswEr:-

Perimeter of square = d) 400 m

$\rule{200}{3}$

Given:-

• Area of square shapped field = 10000 m²

To find:-

• Perimeter of field = ?

Solution:-

⋆ DIAGRAM:-

$\setlength{\unitlength}{1.05 cm}}\begin{picture}(12,4)\thicklines\put(5.6,9.1){ A }\put(5.6,5.8){ B }\put(9.1,5.8){ C }\put(9.05,9.1){ D }\put(4.5,7.5){ a\:m }\put(7.1,5.3){ a\:m }\put(9.5,7.5){ a \:m }\put(7.1,9.5){ a \:m }\put(6,6){\line(1,0){3}}\put(6,9){\line(1,0){3}}\put(9,9){\line(0,-1){3}}\put(6,6){\line(0,1){3}}\end{picture}$

Let the side of field be a m

We know,

☛ Area of square = (Side)²

Therefore,

⇒ a² = 10000

⇒ a = √(10000)

⇒ a = √(100)²

⇒ a = 100 m

So, side of squared field = 100 m

$\rule{200}{1}$

Now perimeter of field:-

We know,

☛ Perimeter of square = 4 × Side

⇒ Perimeter = 4 × 100

⇒ Perimeter = 400 m

Therefore,

Perimeter of squared field = 400 m.

So, Answer :- d) 400 m

$\rule{250}{3}$
