Question

In a trapezium the parallel sides measure
40 and 20 cm calculate the area
of trapezium if its non-parallel sides are
equal having length of 26 cm.​

Answer 1

Step-by-step explanation:

length=40cm

breadth=20cm

height =26cm

area of trapezium= 1/2 (l+b)×h

=1/2 (40+20)×26

=1/2×60×26

=30×26

=780 square cm

Answer 2

Answer:

The parallel sides of an isosceles trapezium = 40 cm and 20 cm.

The equal sides = 26 cm.

The distance between the parallel sides = [26^2-{(40–20)/2}^2]^0.5

= [676–10^2]^0.5

= (676–100)^0.5

= 576^0.5

= 24 cm.

Area of trapezium = (40+20)*24/2 = 720 sq cm. Answer.
