Solution


Q.

The diagram alongside shows a trapezium enclosed within a circle with a radius of 3 cm.

The length of AD is 5.5 cm and length of BC is 4 cm.

Based on the above information, answer the following questions:

 

(ii) Find area of trapezium ABCD.
1 16.624 cm2  
2 16.615 cm2  
3 16.625 cm2  
4 15.625 cm2  

Ans.

(3)

We have distance between parallel lines AD and BC = 3.5 cm, h = 3.5 cm

Also, AD=5.5 cm, BC=4 cmArea of trapezium:=12×(AD+BC)×h=12×(5.5+4)×3.5=12×9.5×3.5=16.625 cm2
