Question

The non-parallel sides of a trapezium are equal, each being 26 cm . The parallel sides are 40 cm and 20 cm . Find the area of trapezium

Answer 1

Answer:

Step-by-step explanation: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.
