Problem

Peter wants to fence the park in front of his house on three sides, which measure 172 m 45 cm, 235 m 10 cm, and 310 m 39 cm. Find the total length that is to be fenced.

Step

The measurements of the three sides of the park

172 m 45 cm , 235 m 10 cm and 310 m 39 cm

Hint

First, convert the centimeters to meters (1 meter = 100 centimeter)

172 m 45 cm = 172 + 0.45 = 172.45 m

235 m 10 cm = 235 + 0.10 = 235.10 m

310 m 39 cm = 310 + 0.39 = 310.39 m

Step

Now, add the lengths together in meters

172.45 + 235.10 + 310.39

Step

After addition, we get

717.94 m

Step

Now, convert the total length into kilometers:

\$717.94 / 1000\$(1 km = 1000 m)

Step

After simplification, we get

0.71794 km

Step

The total length of the park that is to be fenced is 0.71794 km
