Question

Find the perimeter of the room. Convert the measurments into Meters before finding the perimeter. Round to the nearest tenth

please help!!!​

Answer 1

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.
