What is the formula for calculating the trapezoid area?
Half the sum of the parallel sides, times the height between them, that is how you calculate the area of a trapezium.And that is what we learnt at school (to the tune of pop goes the weasel.)______________Here's some more detail, for those who want it:For a trapezoid where h is the height (ie: the distance between the two parallel sides), and a & b are the lengths of the two parallel sides:Area = h (a + b) / 2Proof:If you look at a trapezoid sitting on the longer of its two parallel sides, you will see that it's actually a rectangle in the middle, with a right-angled triangle on each side.The area of the rectangle would be:h x a (where a is the shorter parallel side)For the two right-angled triangles, if c and d are the lengths of the perpendicular sides, then the areas are:(h * c) / 2 and(h * d) / 2So, we add the two triangle areas together, and cancel:(h * c + h * d) / 2= h (c + d) / 2This can be substituted for the following, since in a trapezoid a + c + d = b, hence c + d = b - ah (b - a) /2So, the total area of the trapezoid is the sum of the two formulas:h (b - a) / 2 + h * a(multiply the "h * a" part by 2, and divide be 2 as well, to get a common denominator):= h (b - a) / 2 + 2ha / 2= h (b - a + 2a) / 2= h (b + a) / 2So, there's your proof. A little complicated, but hopefully you get the idea.

How do you explain yourself in a math answer?
You explain yourself in a math answer by justifying your actions with the use of properties, definitions, theorems and axioms/postulates. This is called a "proof", and represents the foundation of modern mathematics. For example, here is a simple proof that FOILing two binomials is the same as polynomial multiplication: Consider the binomials (a*x + b) and (c*x +d) We know that: (a*x + b) * (c*x + d) = (a*x + b) * c*x + (a*x + b)*d by the Distributive Law of Multiplication. Applying the Distributive Law of Multiplication again a second time, we know that: (a*x + b) * c*x + (a*x + b) * d = a*x*c*x + b*c*x + a*x*d + b*d. Applying the Commutative Law of Multiplication and simplifying, we have: a*x*c*x + b*c*x + a*x*d + b*d = a*c*x^2 + b*c*x + a*d*x + b*d Applying the Commutative Law of Addition, we have: a*c*x^2 + b*c*x + a*d*x + b*d = a*c*x^2 + a*d*x + b*c*x + b*D Since "=" is an equivalence relation, we know the following by transitivity (if h = i and i = j then h = j): (a*x + b)*(c*x + d) = a*c*x^2 + a*d*x + b*c*x + b*d That is, the multiplication of two binomials is equal to the summation of the first terms multiplied, the outer terms multiplied, the inner terms multiplied and the last terms multiplied - hence FOIL (First Outer Inner Last). The above proof is an example of a "direct proof". We showed that two polynomials are equal to each other. THere are other methods for proving: Proof by Cases, Proof by Contradiction, Proof by Contrapositive, Proof by Induction and Proof by Logical Equivalency.
