Answer:
13.3 = ?
Step-by-step explanation:
The perimeter is the sum of the sides
P = 7.2+ 4.1 + 4.1+ ? + 1.9+ 7.2+ 1.9+12.8+4.1+4.1
We know there perimeter is 60.7
60.7 = 7.2+ 4.1 + 4.1+ ? + 1.9+ 7.2+ 1.9+12.8+4.1+4.1
Combine like terms
60.7 = 47.4 + ?
Subtract 60.7 from each side
60.7 - 47.4 = ?
13.3 = ?
