Answer:
The area of the room and its uncertainty in square meters is:
15.642±0.040 
Step-by-step explanation:
We know the area of a rectangular room is the multiplication of the length and width:
Now we need to know the uncertainty, the uncertainty of a multiplication is:
(1)
: Area uncertainty
: Length uncertainty
: Width uncertainty
A: Area of the room
L: Length
W: Width
Clearing the uncertainty of the area:
(2)
The area of the room and its uncertainty in square meters is:
15.642±0.040
160 i believe. to find the area of a triangle act like its a square and divide in half. for squares multiply base by height.
take the area of each shape and add it up
1700000000You see there is no decimal... so we have to put one. Whenever there is no decimal, its just add the end ;)
Now our number has to be greater then 1 but less than 0.
So as you can see 17 is greater then 10. So what about 1.7? Yes thats greater then one but less than 0!
So lets see how many spaces it takes to move the decimal there.
I got 9.
So then we do this:
1.7*10^9
Got it?
