Question

the length of a rectangle is twice its breadth and its area is 400 CM square find the length and breath of the rectangle

Answer 1

Given:-

• The length of rectangle is twice its breadth.

• Area of rectangle is 400 cm².

To find out:-

Find the length and breadth of given rectangle.

Formula used:-

Area of rectangle = Length × Breadth

Solution:-

Let the breadth be x

Then,length = 2x

According to the question ,

Area of rectangle = 400 cm² [ Given ]

⇒ Length × Breadth = 400

★ Substituting the values of length and breadth in the above formula,we get:

⇒ x × 2x = 400

⇒ 2x² = 400

⇒ x² = 400/2

⇒ x² = 200

⇒ x = √200

⇒ x = 14.14 cm

Now,

★ Breadth = x = 14.14 cm

★ Length = 2x = 2 × 14.14 = 28.28 cm

Thus,the length and breadth of rectangle are 28.28 cm and 14.14 cm respectively.

Answer 2

Answer:

YOUR QUESTION :

the length of a rectangle is twice its breadth and its area is 400 CM square find the length and breath of the rectangle.

YOUR ANSWER :

Given:-

• The length of rectangle is twice its breadth.
• Area of rectangle is 400 cm².

To find out:-

• Find the length and breadth of given rectangle.

Formula used:-

• Area of rectangle = Length × Breadth

Solution:-

• Let the breadth be x

• Then,length = 2x

Area of rectangle = 400 cm² [ Given ]

=> Length × Breadth = 400

=> x × 2x = 400

=> 2x² = 400

=> x² = 400/2

=> x² = 200

=> x = √200

=> x = 14.14 cm

ANS :

1) Breadth = x = 14.14 cm

2) Length = 2x = 2 × 14.14 = 28.28 cm
