9 cm^2

Step-by-step explanation:

you would do 3 * 3, which would give you 9, then divide it by 2 to get 4.5, then add 4.5 to itself, and that is your answer

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
