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.
If you have a hexagon and you put a line in the middle what would the shapes called?
Trapezoid.
What are some pre-algebra formulas?
For circle area: pi times radius squared. For circle circumference: 2 times pi times radius, for Square area: take the length of one side (doesn't matter which one because they are all equal) and square the number. For parallelogram area: take the base (bottom) and times it by the height (usually going up the middle.) For triangle area: take half of the base or height and times it by the whole base or height. For trapezoid area: the equation is half ( a side plus b side) times height. for rectangle area: width times height.

How calculate parallel middle body of the ship?
Well, honey, calculating the parallel middle body of a ship is as simple as dividing the ship's length by 3. Why? Because that's just how naval architects like to keep things spicy. So, grab a tape measure, do some math, and voilà, you've got yourself the parallel middle body of that ship. Now go conquer the high seas, sailor!
How do you measure area of trapezoid?
To measure the area of a trapezoid, you can use the formula: Area = (1/2) * (sum of the lengths of the parallel sides) * (height). Simply add the lengths of the two parallel sides together, multiply by the height, and then divide by 2 to find the area of the trapezoid.
Given the median QR and trapezoid MNOP what is the value of x Top x plus 8 Middle 24 Bottom 5x plus 4?
Not too sure of your question but the area of a trapezoid is:- 0.5*(sum of parallel sides)*height Hope the given formula helps you
What shape is a trapezoid cut in half?
That depends where the cut is made if it's from vertex to vertex it will make 2 triangles otherwise it will make 2 quadrilaterals

How much lines of symmetry does a trapezoid have?
If it is an isosceles trapezoid, then there is only one line of symmetry, right down the middle of it from top to bottom. If it is a plain old trapezoid with no congruent sides, then there are no lines of symmetry.
How do you divide a trapezoid into 2 equal parts?
Well, isn't that a happy little question! To divide a trapezoid into two equal parts, you can draw a line from the midpoint of one of the non-parallel sides to the midpoint of the opposite side. This will create two equal areas within the trapezoid, just like magic! Just remember, there are no mistakes, only happy little accidents in the world of art and geometry.
