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
-
A.
12cm2 -
B.
28(frac{1}{2})cm2 -
C.
16cm2 -
D.
10cm2 -
E.
6cm2
Correct Answer: Option E
Explanation
Area of the triangle XYZ = (frac{1}{2})bh = (frac{1}{2})ZY x XY
= (frac{1}{2}) x 3 x 4
= 6cm2.
