the area of a rectangle is 42 square meter. the lenght is 7 meter . what is the perimeter of the rectangle​

Answer»

ANSWER:

The perimeter is 26 m

Step-by-step explanation:

Given :

AREA = 42 m²

Length = 7 m

To find :

The Perimeter

Solution :

To get the perimeter, we need to find the breadth of the rectangle first.

★ Breadth -

Let the breadth be y

⇒ Area = Length × Breadth

⇒ 42 = 7 × y

⇒ 42 = 7Y

⇒ y = 42/7

⇒ y = 6

Breadth = 6 m

\rule{300}{1.5}

★ Perimeter = 2(Length + Breadth)

⇒ 2(7 + 6)

⇒ 14 + 12

⇒ 26 m

Therefore, the perimeter is 26 m.
