Answer:
Area of the trapezium ABDE = 30 cm²
Step-by-step explanation:
Area of a trapezium = 
Here,
and
are the parallel sides of the trapezium
h = Distance between the parallel sides
From the picture attached,
ΔCAE and ΔCBD are the similar triangles.
So by the property of similarity their sides will be proportional.


CE = 
CE = 12 cm
Therefore, DE = CE - CD
DE = 12 - 8 = 4 cm
Now area of trapezium ABDE = 
= 
= 30 cm²
Therefore, area of the trapezium ABDE = 30 cm²
2/3 x 1/5 = 2/15 that is the answer

i wish i could help but its kind of over a minute but the answer is C
Answer:
a. tanB= 3/2
Step-by-step explanation:
tanA= p/b =:2/3
For angle A,
p= 2
b=3
For angle B,
p = 3
b=2
So, TanB = 3/2
