Answer: 8.2 m

Step-by-step explanation:

First we need to convert the measurements of the two sides to meters using the fact that
100 cm = 1m.


230 cm = 2.3 m \\178 cm = 1.78 m

Now we can use the formula for perimeter to solve the problem:


2(S1+S2) = 2(1.78+2.3) = 2(4.08) = 8.16 m

Finally, if we round
8.16 to the nearest tenths, we get the answer of 8.2 m.
