The length of a rectangle is twice its width. If perimeter of rectangle is 42 metres find, the area of the rectangle?​

Answer»

Answer:

The Area of the Rectangle is 98 m²

Step-by-step explanation:

Given :

Length of the Rectangle = Twice it's Breadth (WIDTH)

Perimeter of Rectangle = 42 m

To Find :

The Area of the Rectangle

Solution :

Consider the Breadth as x

Consider the Length as 2X

★ Perimeter of Rectangle = 2(Length + Breadth)

⇒ 2(2x + x) = 42

⇒  4x + 2x = 42

⇒  6x = 42

⇒  x = 42/6

⇒  x = 7

\rule{300}{1.5}

★ Value of 2x

⇒  2 MULTIPLIED by 7

⇒  14

Length = 14 m

Breadth = 7 m

\rule{300}{1.5}

★ Area of the Rectangle = Length Breadth

⇒ 14 × 7

⇒ 98

∴ The Area of the Rectangle is 98 m²
