Answer:
12
Step-by-step explanation:
Sides are in the ratio 28:7,
Which is also 4:1
The length of sides of the bigger triangle are 4 times the length of the smaller one.
6x+28 = 4(25)
6x+28 = 100
6x = 72
x = 12
Number of flowers in the garden of Christina = 50
The ration of roses to daisies in Christina's garden = 1:4
Let us assume the common ratio to be = x
Then
x + 4x = 50
5x = 50
x = 50/5
= 10
Then
Number of roses in the garden of Christina = 1 * 10
= 10
Number of daisies in the garden of Christina = 4 * 10
= 40
So the number of roses in the garden of Christina is 10 and the number of daisies is 40.
