Question

area of trapezium explain it ​

Answer 1

1/2×(sum of parallel side ) × height

Answer 2

Step-by-step explanation:

When the two trapezoids are combined in this way, the result is a parallelogram, which has two pairs of opposite, congruent sides.

Recall that the area of a parallelogram is its altitude (h) times the length of either base. From the figure above we see that both base lengths are equal to b1+b2. So the area of the parallelogram is

parallelogram area = ( b 1 + b 2 ) · h

Since this is the area of two trapezoids we have to divide this by two, giving

trapezoid arae =

$\frac{(b1 + b2) \times h}{2}$

Finally, we get:

Area of trapezium => ½×(sum of parallel sides)×height.
