Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
Area: [tex]12x+66[/tex]
It will actually look like this...[tex]A=12(5.5+x)[/tex] so if you distribute you'll get the blanks.
Perimeter: [tex]2x+90[/tex]
It will actually look like this...[tex]P= 2(5.5+x)+2(12)[/tex] so once you distribute the 2's you'll end up with...[tex]66+24+2x[/tex] so if you add the 66 and the 90 you'll get the blanks.
