Answer:
x = 22
Step-by-step explanation:
triangle = 180 degrees
2x + 12 + x + 54 + 3x - 18 = 180 degrees
combine like terms
6x + 12 + 54 - 18 = 180
6x + 48 = 180
<u> -48 -48</u>
6x = 132
divide by 6
x = 22

Perimeter of rectangle = 2(l+w)
So, 54cm = 2(l+9cm)
=> 54cm = 2l + 18cm
=> 54cm - 18cm = 2l
=> 36cm = 2l
=> 36cm/2 = l
=> 18cm = l
The third option is correct
