Answer:

The slate it 14" by 18"

1.  64

2. 192

Step-by-step explanation:

When you add 14 plus 14 you get 28 then add both of your 18 together and you get 36 then add 28 plus 36 and you get 64. 64 times 3 is 192

Answer 2

1. Add 3 inches to each side, so a total of 6 inches on the height and 6 inches on the width

8 +6 = 14

12 + 6 = 18

Perimeter = 14 + 14 + 18 + 18 = 64 inches.

2. Multiply the perimeter from above by 3:

64 x 3 = 192 inches.
