The perimeter of the figure below is 113.7 cm.
Find the length of the missing side.

The length of the missing side it 8.8.
Since we know the equation, we can find the missing side.
=> 113.7 = 38.2 + 2(7.9) + 19.1 + 3(10.6) + x
=> 113.7 = 38.2 + 15.8 + 19.1 + 31.8 + x
=> 113.7 = 104.9 + x
=> x = 8.8
Therefore, the length of the missing side it 8.8.
