Answer:
54 scarves
Step-by-step explanation:
4 hours-9 scarves
8 hours-18 scarves
12hours -27 scarves
16 hours-36 scarves
20 hours-45 scarves
24 hours-54 scarves
pattern: h+4 (hours) s+9 (scarves)
36/12=3 Which give you the enlargement of the smaller triangle to the bigger one.
You work out the missing side by putting it into an equation:
3(x-10)=39
Then solve it.
First expand the brackets:
3x-30=39
The rearrange to get x on its own and that will be your answer:
3x=39+30
3x=69
x=69/3
x=23

Answer: 228 feet squared
How: To get the area of the entire field, multiply 25•36 to get 900. To find length of the area inside the path, you have to subtract 2 feet from both sides of 25, which is also 4 feet, to get 25-4=21. To find the width of the area inside the path, you have to subtract 2 feet from both sides of 36, which is also 4 feet, to get 36-4=32. You multiply 21•32 to get 672, which is the area of the field inside of the path. To find the area of the path, you subtract the total area of the field and the path together, which is 900, by 672 to get 228 feet squared.
