Answer:
A
Step-by-step explanation:
Given 2 similar figures with sides in the ratio a : b
Then the ratio of their areas is a² : b²
Hence
ratio of sides = 2 : 9, then
ratio of areas = 2² : 9² = 4 : 81 → A
The perimeter of the shape is 30 add all the sides

Here's what i found online:
<span>a/3+4=6
We simplify the equation to the form, which is simple to understand
<span>a/3+4=6
Simplifying:
<span> + 0.333333333333a+4=6
We move all terms containing a to the left and all other terms to the right.
<span> + 0.333333333333a=+6-4
We simplify left and right side of the equation.
<span> + 0.333333333333a=+2
We divide both sides of the equation by 0.333333333333 to get a.
<span>a=6
Hope this helped :-)</span></span></span></span></span></span>
