Let the height be x:- If: 0.5*(8+20)*x = 98 square units Then: x = 98*2/8+20 => x = 7 Therefore height of the trapezoid is: 7 units Check: 0.5*(8+20)*7 = 98 square units
If you mean to divide one fraction by another, the easiest is to multiply your numerator fraction by the reciprocal of your denominator fraction. For example, if: x = (a / b) / (c / d) then: x = (ad)/(bc)

If you have something like '[a/b] / [c/d ] ' It means the 'a/b' is divided by 'c/d' Remember the rule for division of fractions ; CHANGE THE SIGN TO MULTIPLY(X) AND INVERT (TURN OVER) THE DENOMINATING FRACTION. /Then proceed as multiplying fraction. Hence [a/b] X [ d/c ] = ad/bc The answer. !!!!! e.g. 2/3 divide 1/9 => 2/3 X 9/1 = 2/1 X 3/1 = 6/1 = 6 THE ANSWER!!!!!
If fraction X = a/b, and fraction Y = c/d, you can 'flip' the one you're dividing by (take the inverse) then X/Y which is (a/b)/(c/d) = (a/b)*(d/c) =[a*d] / [b*c] For mixed numbers, it is best to convert to an improper fraction, then do the same procedure as above, I think.

area of a square :c x c 16 x 16=256
Let x be the parameter to be taken square root. a = 0 b = x loop: c = (a+b)/2 if c*c > x then b = c else a = c Repeat until accurate enough result is obtained in c or until c*c equals x.
Given the median and trapezoid MOPN, what is the value of x?
The question is a bit vague to follow but in general the area of a trapezoid is 0.5*(sum of parallel sides)*height and the area of a square is a side squared.
A negative fraction Algebraically a/b X -c/d = -ac/bd
If you mean to divide one fraction by another, the easiest is to multiply your numerator fraction by the reciprocal of your denominator fraction. For example, if: x = (a / b) / (c / d) then: x = (ad)/(bc)
It depends on what x represents, and what information you have about the trapezoid.
