A mixed number of the form 
can be turned into an improper fraction by using the fact that a mixed number is really het whole number plus its fraction part, so
Then do the usual procedure for adding fractions via common denominator.
For example, to convert the mixed number 
into an improper fraction, we have
To add 
, we need 
to have a denominator of 4, so we multiply the numerator and denominator by 4 to get
Therefore,
0 is the answer to the question.

Answer:
10 m
Step-by-step explanation:
If the area of a square is 50 m2, then the length of each side will be 
m, to get the diagonal length, after dividing the square by joining the points of the diagonal with a line, it forms two right angles with length m each.
the diagonal length represent the hypotenuse side of each of the right angle, knowing the pythagoras theorem:
, so we have:
diagonal = 10 m
