Question

The area of a room is 60 m a m. Ifits breadt is 4 metres, what is its length?​

Answer 1

Required Answer :

• The length of the room = 15 m

Given :

• Area of room = 60 m²

• Breadth of the room = 4 m

To find :

• The length of the room = ?

Explanation :

In this question, we are given the area and breadth of a room which are 60 m² and 4 m respectively and we need to find the length of the room. So, we will use the formula of area of rectangle.

Formula of area of rectangle :

• Area of rectangle = l × b

Where,

• l denotes the length of the rectangle

• b denotes the breadth of the rectangle

Solution :

Substituting the given values in the formula :

→ Area of room = l × b

→ 60 = l × 4

→ 60/4 = l

→ 30/2 = l

→ 15 = l

Therefore, the length of the room = 15 m

Answer 2

Question :-

The area of a room is 60 m² and its breadth is 4 m. Find the length of the room.

Answer :-

Length (l) of the room is 15 m.

Solution :-

Let the length be l and the breadth be b.

Area = 60 m²

Breadth (b) = 4 m

$\large\boxed{\displaystyle\rm\green{Area\: of\: \:Rectangle = l × b}}$

Substituting the given values, in the formula;

$⟼60 = l × 4 \\ \\ ⟼\dfrac{60}{4} = l \\ \\ ⟼ \: 15 = l$

Therefore, the length of the room is 15m.
