In right angled \(\triangle\) NMP
NM^2 = NP^2 - MP^2
= 26^2 - 24^2
=676 - 576
= 100
NM= 10

area of \(\triangle\) MNP = 1/2 *NM *MP
= 1/2 *10 * 24
= 120

Answer C

First simply calculate MN using Pythagoras Theorem i.e. h^2=p^2+b^2
MN=\sqrt{26^2-24^2}
=10
Now
Area of MNP=1/2*MN*MP=1/2*24*10=120 units

It is good to remember the first few pythagorean triplets and their multiples.
Note that 24 and 26 are second positive multiplies of 12 and 13. So this must be the 5, 12, 13 triplet. The third side must be 5*2 = 10

Area of MNP = (1/2)*10*24 = 120 square units.

Answer (C)

I like to think of this step as
= 26^2 - 24^2
= (26 - 24)(26 + 24)
=2*50
=100

I find it saves time
