Question

which of the 2 room is bigger, one whose length and breadth of the floor are 10m and 8.5m or one whose length and breadth of the floor are 9.5 m and 9 m?

Answer 1

Answer:

Room 2 is bigger than Room 1.

Step-by-step explanation:

Length of Room 1  = 10 m

Breadth of Room 1 = 8.5 m

Area of Room 1 = (Length of Room 1) × ( Breadth of Room 1)

                          =  10 m × 8.5 m

                          = 85 $m^2$

Length of Room 2  = 9.5 m

Breadth of Room 2 = 9 m

Area of Room 2 = (Length of Room 2) × ( Breadth of Room 2)

                          =  9.5 m × 9 m

                          = 85.5 $m^2$

Let us assume that the heights of both Room 1 and Room 2 are the same. So in that case the area of Room 2 is bigger than of Room 1 by 0.5 $m^2$.

Therefore we can say that Room 2 is bigger than Room 1.

Answer 2

Given :

• Which of the 2 room is bigger, one whose length and breadth of the floor are 10m and 8.5m.

ㅤㅤ

Find :

• Whose length and breadth of the floor are 9.5 m and 9 m?

ㅤㅤ

Formula :

★ Area = Length × Breadth.

ㅤㅤ

Calculations :

→ Area = 10 × 8.5

→ Area = 86 m²

ㅤㅤ

→ Area = 9.5 × 9

→ Area = 85.5 m² [Bigger room]

ㅤㅤ

Therefore ,

• The area of second room is little much bigger than the first room.
