what is the distance between points m and n? meters

Explanation:

Step1: Identify the relevant sides

We know that $KM = ML= 10.7$ m and $JN=NL = 7.4$ m.

Step2: Use the mid - segment theorem

In $\triangle{JKL}$, $MN$ is parallel to $JL$ and $MN=\frac{1}{2}JL$. Since $JL=JN + NL=7.4+7.4 = 14.8$ m, then $MN=\frac{1}{2}\times14.8$ m.

Step3: Calculate the distance

$MN = 7.4$ m.

Answer:

$7.4$
