Question

The Parallel sides of a trapezium aee 25 cm and 13 cm, its non-Parallel sides are equal, each being 10 cm. Find the area of the trapezium?

Answer 1

tur Area of trapezium of od 58

Answer 2

Given that a=13, b=25, and c=d=10

height of the trapezium is h = sqrt of (10squared - [(b-a)/2]squared) = sqrt of (10 squared - (25-13)/2 squared)

=sqrt of (100-36) = 8

area of trapezium = (a+b)/2 x height

= (25+13)/2 x 8

= 19x8

=152 cm squared

Ans: Area of the trapezium is 152 cm squared
