Given => PQ = 9 unit
PR = 7 unit
QR = 8 unit
To find => Area of triangle PQR
We can find area of triangle by Heron's Formula.
Where,
s = (9+7+8)/3
= 24/3
= 8
and,
a = 9
b = 7
c = 8
Heron's Formula =

=

=

=

=

Area of triangle = 2i√2 units
Hope this helps!
Answer: 2538
Step-by-step explanation:
12*21/2
126
126/1*41/2
2538
M(m^4+m^2-6)
This is the max you can factorize it, it cannot be factorized any further.
So this problem is actually fairly simple. The only thing you need to do is take the cube root of 1300. The cube root of 1300 is roughly 10.9. Your answer should be about 10.9 in.
