What is the formula for area of a trapeziod?

Answer 1

#A_"trapezoid"=(b_1+b_2)/2xxh#

An easy and intuitive way to think about this formula is in how it is similar to the area of a rectangle.

In a trapezoid, the bases are different lengths, so we can take the average of the bases, #(b_1+b_2)/2#, to find the "average" base length. This is then multiplied by the height. In a rectangle, the bases are always the same length, but here, imagine taking some from the longer base and giving it to the shorter base.

The formula for the area of a trapezoid is ( A = \frac{1}{2}h(a + b) ), where ( A ) is the area, ( h ) is the height, and ( a ) and ( b ) are the lengths of the two parallel sides.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
