It is: 0.5*(sum of its parallel sides)*height
area of trapezium=1/2{a+b}h
Area = 0.5*(sum of parallel sides)*heightNote: A trapezium in the UK is known as a trapezoid in the USA
1/2 x (a+b) x hA =is the average number of parallel sidesB = is the distance between themh=is the height
No because the formula for finding the area of an oval, which is an ellipse, is quite different
1 - (a+b) X h 2
Area = (1/2)*(sum of the parallel sides)*(distance between them)
the formula for finding the area of an ellipse is add it then multiply and subtract that is the final
Area = 0.5*(sum of parallel sides)*height
You can visualize the formula for the area - I guess that's what you mean - as multiplying the height by the average width.You can also derive it more formally, by splitting a typical trapezium into rectangles and triangles.
If you mean the area, this can be derived in different ways. Most school books should show some derivation of the formula.* It's quite easy to see intuitively (though perhaps a bit more tricky to prove) that the area should be equivalent to the corresponding rectangle, where the width of the rectangle is set equal to the average width of the trapezium. The average, in this case, is the average of the longer and the shorter side (of the two parallel sides). Perhaps the formula was originally derived this way, though it's hard to be sure. * You can divide a trapezium into rectangles and triangles, and derive the formula from there. * Of course you could also use integration, though in this case, this is more complicated than necessary.
A trapezium is a quadrilateral (has four sides). Two sides are parellel, but the other two are not. To find the area of it, the formula is: 1/2 h(a+b)
what is the formula to finding the total surface area of a rhomboid?!
