Triangular 65304

The triangular plot has dimensions of 90m, 110m, and 130m. The land is drawn on a map with a scale of 1:2000. Find the lengths of its sides on the map in centimeters.

Correct answer:

a =  4.5 cm
b =  5.5 cm
c =  6.5 cm

Step-by-step explanation:

$$\begin{gathered} A=90\text{m}\to \text{cm}=90\cdot 100\text{cm}=9000\text{cm} \\ B=110\text{m}\to \text{cm}=110\cdot 100\text{cm}=11000\text{cm} \\ C=130\text{m}\to \text{cm}=130\cdot 100\text{cm}=13000\text{cm} \\ M=2000 \\ a=A/M=9000/2000=4.5\text{cm} \end{gathered}$$

$b=B/M=11000/2000=5.5\text{cm}$

$c=C/M=13000/2000=6.5\text{cm}$
