Question

the parallel sides of a trapezium are 25 cm and 10cm while its non parallel sides are 14 cm and 13 cm find the area of the trapezium​

Answer 1

1) Find with Heron’s formula the area, A, of the 13–14–15 triangle.

- 2) Solve A(triangle) = (base * height)/2 for height, h.

- 3) Apply the formula for area of trapezium:

A(trap) = (1/2)*[base(1) + base(2)]*h
