Answer:
The base is 11 cm.
Step-by-step explanation:
The formula for the area of a triangle is 
. If we plug in what we know to this equation, we are left with 
, which we now need to simplify.
First, we combine like terms.
Then, we can eliminate the 
and 
on the right side of the equation, since they cancel each other out.
Finally, we take the square root of both sides of the equation and find our answer:
32.45 is most precise . Precise means how many points after decimal is reached. Accurate means how close your measurement of a value is that to the true value. Eg :Say 35cm is the measure of length of a body and a person got the measurement to be 34 . Another person2 got the measurement to be 32.88 . So in this case the first person has an accurate answer as he is close to the true value 35 , but person2 is more precise as he has two decimal places.
