In the diagram, XZ is the diameter of a circle's radius \(\frac{5}{2}\). If XY is 4cm, then the area of the triangle XYZ is
Attached Figure / Diagram
A
12cm2
B
28\(\frac{1}{2}\)cm2
C
16cm2
D
10cm2
E
6cm2
Verified Correct Answer: E.
Step-by-Step Mathematical Solution
Area of the triangle XYZ = \(\frac{1}{2}\)bh = \(\frac{1}{2}\)ZY x XY
= \(\frac{1}{2}\) x 3 x 4
= 6cm2.
