Question

the length of a rectangle is twice its breadth.If perimeter of rectangle is 66 cm,find its length and breadth.​

Answer 1

Answer:

Let breadth=x

length=2x

A/q

=2(2x+x)=66cm

=2*3x=66

=6x=66

=x=11

Length=22cm

Breadth=11cm

Answer 2

Answer:

Length is 22 cm and Breadth is 11 cm.

Step-by-step explanation:

Given :

Length of the rectangle = twice its Breadth

Perimeter = 66 cm

To find :

Its dimensions

Solution :

Let the -

• Breadth be y
• Length be 2y

★ Perimeter = 2(Length + Breadth)

⇒ 66 = 2(2y + y)

⇒ 66 = 4y + 2y

⇒ 66 = 6y

⇒ y = 66/6

⇒ y = 11

Breadth = 11 cm

$\rule{300}{1.5}$

★ Value of 2y

⇒ 2(11)

⇒ 22

Length = 22 cm

$\therefore$ Length is 22 cm and Breadth is 11 cm.
