Answer:
acc to ques....perimeter of figure= 3a^2+15a+9
let missing dimension be x
= x+10a-2+a^2-7+5a=3a^2+15a+9
x+15a+a^2-9=3a^2+15a+9
x=2a^2+18
To solve for y, apply the distributive property:

Then, subtract 12 from both sides and you will get:

Then solve for y, by dividing both sides by 10.
Your final answer will be y=1.2
