Answer:
3 cm
Step-by-step explanation:
The ratio of areas of similar figures is the square of the ratio of linear dimensions. That means the ratio of linear dimensions is the square root of the area ratio. The ratio of the smaller triangle dimensions to the larger is then ...
k = √((8 cm^2)/(18 cm^2)) = √(4/9) = 2/3
Then the corresponding side of the smaller triangle is ...
... k · (4.5 cm) = (2/3)·(4.5 cm) = 3 cm
I would go with Either E or A
Well, if we look at a calculator and ask, what is 8% of 3000$ we get the answer of 240 dollars.
3000 - 8% = 2760 therefor we know it removes 240 dollars. So the commission is 240 dollars.
