Question

Please help me fill in these blanks with the correct answers.

Answer 1

Hello!!! Princess Sakura here ^^

Explanation:

Area:
`12x+66`

It will actually look like this...
`A=12(5.5+x)` so if you distribute you'll get the blanks.

Perimeter:
`2x+90`

It will actually look like this...
`P= 2(5.5+x)+2(12)` so once you distribute the 2's you'll end up with...
`66+24+2x` so if you add the 66 and the 90 you'll get the blanks.
