Hey fam!
Given,
QR = 10cm
Height PQ = 4.4cm
So,
Area triangle PQR = 1/2×b×h
=> 1/2×10×4.4
=>22 cm^2
Now,
PR =11cm
Again,
Area trianglePQR with base PR=>
22= 1/2×b×h
22=1/2×PR× QN
22=1/2×11×QN
22=11/2×QN
There fore,
QN = 4cm
Cheers !
From which standard this question is ...?
idk. 8th or 9th maybe?
angle PQR is not equal to 90 deg as 11^2 = 121 not equal to 10^2 + 4.4^2 = (100 + 19.36 = 119.36)
3.999 First calculate Area of triangle PQR using Hero formula then equate to (1/2) * PR * QN .
what?

Answer: the missing length is 11.84736258
Step-by-step explanation:
it use the Pythagorean theorem
(a)^2+ b^2=c^2
a=4.4
b=11
so
4.4^2+11^2=11.84736258
