Answer 2

Answer:

The Area of the rectangle is 24 cm².

Step-by-step explanation:

Given :

Ratio of the length to breadth = 3 : 2

Perimeter of the rectangle = 20 cm

To find :

Rectangle's area

Solution :

Let the dimensions be -

• Length as 3x
• Breadth as 2x

★ Perimeter = 2(Length + Breadth)

⇒ 2(3x + 2x) = 20

⇒ 6x + 4x = 20

⇒ 10x = 20

⇒ x = $\tt{\dfrac{20}{10}}$

⇒ x = 2

$\rule{300}{1.5}$

★ Value of 3x

⇒ 3(2)

⇒ 6

Length = 6 cm

$\rule{300}{1.5}$

★ Value of 2x

⇒ 2(2)

⇒ 4

Breadth = 4 cm

$\rule{300}{1.5}$

★ Area = Length × Breadth

• Length = 6 cm
• Breadth = 4 cm

⇒ 6 × 4

⇒ 24 cm²

$\therefore$ The Area of the rectangle is 24 cm².
