Answer:
b) 84
Step-by-step explanation:
according to pythogoras theorem
p^2= h^2- b^2
QM^2= MR^2- QR^2
=. 1Ocm^2-4 cm^2
=. 100cm^2 - 16 cm^2
=. 84 cm^2
QM. = √84 cm^2
=. 2*2*3*7
=. 2*2=4

Answer:
Step-by-step explanation:
PR=10cm
QM=QM
∠PMQ=∠QMR=90°
PQ=QR=4cm
from SAS property
PQ/QR=
according to pythagoras theorem
hypotenuse²=side²+other side²
QR²=QM²+MR²
