Question

the parallel sides of a trapezium are 25cm & 13cm & nob parallel sides are 15cm each. Find area of trapezium.​

Answer 1

Answer:

261.06

Step-by-step explanation:

Area of trapezium = 1/2(b1+b2)×H

b1=25cm, b2=13cm, h=?

Here, p= perpendicular, b=base, h=hypotenius

We will find height by the formula of finding perpendicular of a right angle triangle.

(p)²=(h)²-(b)²

(p)²=(15)²-(6)²

(p)²=225-36

(p)²=189

p=root189

p=13.74

Now, putting the values of b1, b2, h in

1/2(b1+b2)×H

=1/2(25+13)×13.74

=1/2×38×13.74

=261.06
