Answer 1

To determine the length of \( KL \) in the similar triangles \( \triangle JKL \) and \( \triangle PKQ \), we can use the property of similar triangles, which states that corresponding sides are proportional.

Given:

• \( KP = 14 \) m
• \( JK = 56 \) m
• \( KQ = 21 \) m

We need to find the length of \( KL \). Since the triangles are similar, we can set up the following proportion based on corresponding sides:

\[ \frac{JK}{KP} = \frac{KL}{KQ} \]

Substituting the known values into the proportion:

\[ \frac{56}{14} = \frac{KL}{21} \]

Calculating the left side:

\[ \frac{56}{14} = 4 \]

So we have:

\[ 4 = \frac{KL}{21} \]

To solve for \( KL \), multiply both sides by \( 21 \):

\[ KL = 4 \times 21 = 84 \text{ m} \]

Therefore, the length of \( KL \) is \( 84 \) m.

Final Answer: 84 m
