Answer:The answer is B
Step-by-step explanation:
first find te height:
1.5/2=0.75 (this will be your "b" of the pythagorean theorem for finding the height)
now do the pythagorean theorem:
a^2+0.75^2=3^2
(height)= 2.905
A= a^2+2a√((a^2/4)+h^2)
a (base edge)= 1.5
h (height)= 2.905
Calculate and you get B as your answer.
Hope this elpsand you get this right!
