Answer:

12

Step-by-step explanation:

We know that AD=BC and that AB=CD. We also know the perimeter of the rectangle ABCD to be 54 units.

From this, we can add up the sides which will be equal to 54 units.

AD+BC+AB+CD=54

2x+2x+3x-3+3x-3=54

10x=60

x=6

Since we are trying to find the length of side BC we substitute this value back into 2x.

BC=2x =2*6=12

Therefore, the length of BC is 12 units.

8.180-65-90=25
180-80-60=40
So, 180-40-25=115.

9.(180-40)divide by 2=70
X=180-70
X=110

10.180-118=62
So, 180-62-90
=28

11.not confident yet

12.180-60=120

13. (180-66)divide by 2 =57
180-57=123
(180-123)divide by 2
=28.5

14.180-68-44=68
180-58-73=49
So,180-68-49=63
(Its the same)
