The value of f(2a) is 8a
<h3>What is a function?</h3>
A function can be defined as a rule or expression that shows the relationship between a dependent and independent variable.
From the information given, we have;
g(a) = 4a
Let's determine the value for f(2a)
a = 2a
Let's substitute the value of a as 2a in the function
g(a) = 4a
g(2a) = 4 ( 2a)
Multiply through
g(2a) = 8a
Thus, the value of f(2a) is 8a

Ratio of areas of similar triangles is 9 : 25.
Solution:
Given data:
Ratio of sides of two similar triangles = 3 : 5
To find the ratio of areas of the triangles:
We know that,
<em>In two triangles are similar, then the ratio of their area is equal to the square of the ratio of their sides.</em>



Ratio of areas of similar triangles is 9 : 25.
