Question

one room length 12.8 and breadth equals to 850 CM inside that room there is a bad length is 300 cm and breadth is 400 cm find the remaining surface area of the room and the answer will be in cm​

Answer 1

Answer:

$Area = 968000cm^2$

Step-by-step explanation:

To be able to answer this question properly. I'll assume the length of the room is in meters.

So for the room, we have:

$Length = 12.8m$

$Breadth = 850cm$

For the bed, we have:

$Length = 300cm$

$Breadth = 400cm$

First, we calculate the surface area of the room.

$A_1 = 12.8m * 850cm$

Convert all units to cm

$A_1= 12.8*100cm * 850cm$

$A_1= 1 088 000 cm^2$

Next, we calculate the area of the bed

$A_2 = 300cm * 400cm$

$A_2 = 120000cm^2$

The area of the space left  is the difference between A1 and A2

$Area = A_1 - A_2$

$Area = 1088000cm^2 - 120000cm^2$

$Area = 968000cm^2$
