G
Step-by-step explanation:
We can find a missing length of a triangle using a Pythagorean theorem if and only the triangle is a right angled triangle.
The side of the missing length is:
a^+b^=c^
2^+4^=c^
4+16=c^
20=c^
Area of a triangle = 
r = diameter/2
so area = pi * (13/2)^2
= 3.14*6.5*6.5 = 132.665
r = diameter/2
so area = pi * (13/2)^2
= 3.14*6.5*6.5 = 132.665
