Answer:
The length of sides KM, LM and KN are and 16 respectively. The area of KLMN is
square unit.
Step-by-step explanation:
According to given information: KLMN is a trapezoid, ∠N= ∠KML, , ME ⊥ KN, KE=8
.
Use pythagoras theorem is triangle EKM
Let angle N and angle KML be θ.
Since angle KML and angle MKE are alternate interior angles, therefore angle MKE is θ.
In triangle KME,
.... (1)
In triangle KNE,
.... (2)
Equate (1) and (2),
The length of side KN is
Sides LM:KN are in the ratio 3:5. Let the side lengths are 3x and 5x respectively.
The area of KLMN is
Therefore length of sides KM, LM and KN are and 16 respectively. The area of KLMN is
square unit.
