Answer:
<h3>The answer is 4.9cm</h3>
Step-by-step explanation:
To find the perpendicular distance between them that's the height we use the formula

where
a and b are the parallel sides of the trapezium
h is the perpendicular distance
From the question
Area = 31.5cm²
a = 7.5 cm
b = 5.3 cm
Substituting the values into the above formula we have



Divide both sides by 6.4

h = 4.921875
We have the final answer
<h3>h = 4.9cm</h3>

Answer:
18:19
Step-by-step explanation:
Given that,
The radius of circle A = 9 cm
The diameter of circle B = 19 cm
We know that,
Radius = diameter/2
The radius of circle B = 19/2 cm
The circumference of circle A is :
....(1)
And that of circle B is :
....(2)
Dividing equation (1) and (2) :

Hence, the ratio of circumferences of Circle A and Circle B is 18:19.
