Step-by-step explanation:
=2* ( l+b )
=2* ( 11.37+9.245 )
=2* 20.595
=41.19
The answer is 216 cubic feet. How? All you have to do is multiply every number then divide it by 2. Like this: 2*12*18=432. 432/2= 216 cubic feet.
That would be angle 2. It is on the opposite of angle 7 and it is inside the two parallel lines
Hope this helped!
