Answer:
=9:4
Step-by-step explanation:
The relationship between area and side of triangle is
= (S1/S2)^2= (A1/A2)

=9/4=(A1/A2)
=A1:A2=9:4
Answer:
11/40
Step-by-step explanation:
165 people have blood of type A.

p(blood type A) = (number of people with blood type A)/(total number of people)
p(blood type A) = 165/600 = 33/120 = 11/40
