Answer:
113.04
Step-by-step explanation:
All the triangles are similar, so you have ...
(short side)/(long side) = 3/(CD) = (CD)/12
Multiplying by 12(CD) gives
(CD)² = 3*12 = 36
CD = √36 = 6
The appropriate choice is ...
A) 6
This is the way you solve it

Answer:
The answer to your question is letter c and d.
Step-by-step explanation:
A. 15 × 9 = 135 and 135 – 75 = 60 This answer is not correct because it is not necessary to multiply the # members by the cost of each tree, the answer is incorrect.
B. 3 × 15 = 45 and 45 + 15 = 60 This answer is incorrect because it's using a number 3 that is not part of the data.
C. 45 ÷ 9 = 5 and 5 × 15 = 75
. This answer is correct, first finds the number of tree bought by each member and after that multiply it by the cost of each tree.
D. 45 × 15 = 675 and 675 ÷ 9 = 75 This answer is correct, first found the total cost and after divide it by the number of members.
