$a = 1.84 cm$ $b = 3.02 cm$ $c = 0.82 cm$
Step 1. Let's find the missing side $a$. To find a, all you have to do is subtract the dimensions we already know from the total length of the figure. So, $a = 13.47 cm - 6.74 cm - 4.89 cm$ $a = 1.84 cm$ Step 2. To find $b$, you just need to add both length that we already know from the figure. So, $b = 1.23 cm + 1.79 cm$ $b = 3.02 cm$ Step 3. To find $c$, we just have to subtract what we know from the figure from the total length. Because the "c" appears twice we write it as $2c$. So, $2c = 2.62 cm - 0.98 cm$ $2c = 1.64 cm$ Solve for $c$ $c = \frac{1.64 cm}{2}$ $c = 0.82 cm$
