Given that two parallel sides of trapezium are AB = 77 and CD = 60 cm 

Other sides are BC = 26 m and AD = 25 cm. 

Join AE and CF 

Now, DE ⊥ AB and CF ⊥ AB 

∴ DC = EF = 60 cm 

Let AE = x 

⇒ BF = 77 – 60 – x = 17 – x

 

Area of trapezium = 1/2 (sum of parallel sides) x height 

= 1/2 (60 x 77) x 24

= 1644 cm2
