Answer:
64 ivy stems
Step-by-step explanation:
To solve this problem we can use rule of three:
Firstly we had 72 ivy stems to use in 18 centerpieces, and know we have 16 centerpieces and want to know how many ivy stems we need to use, so:
18 centerpieces -> 72 ivy stems
16 centerpieces -> X ivy stems
18/16 = 72/X
X = 16*72/18 = 64
He needs to use now 64 ivy stems to maintain the ratio.
0.9030 > 0.8736
0.9 > 0.8
so your first option is correct
A = 103 ft²;
A = l²
l² = 103
l = √ 103 = 10.14889 ≈ 10.1
Answer: C ) 10.1 feet
