Question

KLMN is a Parallelogram. LK = 20 cm and KM= 24.

K
L
If KL MN is also a rectangle, find the following measures:
NM =
LN=
QM=
KN=
N
M

Answer 1

NM =LK=20cm(side of parallelogram are equal)

LN=KM=24cm(diagonal of parallelogram are equal)

QM=1/2×24=12cm(diagonal bisect each other)

KN=√(24²-20²)=13.26cm(by Pythagoras theorem)
