Question

The bedroom in a house measures 4.2m by 4.5m and the hall measures 4.6m by 3.8 m. Find the difference in the area of the bedroom and the hall.​

Answer 1

Answer:

area of bed room = 4.2 x4.5=18.9m

area of hall = 4.6 x3.8 = 17.48m

difference =18.9-17.48=1.42m

Step-by-step explanation:

area of bed room = 4.2 x4.5=18.9m

area of hall = 4.6 x3.8 = 17.48m

difference =18.9-17.48=1.42m

Answer 2

Before, finding the answer. Let's find out on how we can find the answer.

• In the question, they have asked us to find the area of the Bedroom and area of hall.
• So, to find the area. We must use the formula of :

$\boxed{\sf Area \: of \: Rectangle = l \times b}$

• After finding the area of both Bedroom and Hall, we must subtract both to find the difference.

Given :

• Length and Breadth of Bedroom = 4.2 m and 4.5 m
• Length and Breadth of Hall = 4.6 m and 3.8 m

To find :

• difference in the area of the bedroom and the hall

Solution :

Area of Bedroom = l × b

                             = 4.2 × 4.5

                             = 18.9 sq.m

Hence, Area of Bedroom is 18.9 sq.m.

---------

Area of Hall = l × b

                    = 4.6 × 3.8

                    = 17.48 sq.m

Hence, Area of Hall is 17.48 sq.m

⇒ Difference :

Difference = Area of Bedroom - Area of Hall

                  = 18.9 - 17.8    

                  = 1.42 m

Hence, difference between Area of Bedroom and Area of Hall is 1.42 m.
