Question

two parallel sides of an isosceles trapezium are 6 cm and 14 cm respectively if the length of each non parallel side is 5 cm find the area of the trapezium​

Answer 1

Answer:

the formula for finding area of trapezium is 1/2× sum of The parallel sides x distance between them gives you area of trapezium

Answer 2

Answer:

In this trapezium, dividing into one rectangle and two triangle

According to figure,length of rectangle is 6 cm and remaining part of largest parallel side of trapezium is divided into two base(4cm) of right -angled triangle .

Now, by Pythagoras theorem

5²= 4²+P²

25-16= P²

P²=9

P=3cm

Ar. of trapezium= 1/2 × sum of parallel side × distance between parallel side

Ar.of trapezium= 1/2×{6+14}×3

=1/2×20×3

=10×3

= 30cm² Ans.
