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>Hope this helps you
To simplify , we have to follow the rules.
Here are the steps to the question:
Step 1: Follow the radical rule.
= a
So, we get .
Next, follow the exponent rule.
=
We get .
The answer is \frac{3}{\sqrt[3]{3} }.
