If altitude CD is sqrt(3) centimeters, what is the number of square centimeters in the area of ACD?

 

 

\(\phantom{area of ABC}\)

ADC = 90°

 

ACD =  60°

 

AD =  sqrt (3)  times longer than  CD  =     3sqrt (3)

 

Area of   ACD =   (1/2) (AD) (CD)  = (1/2) (3sqrt (3) ) * (3)  =    (9/2) sqrt (3)  cm^2
