Rectangles are similar figures, thus if scaled copies of each other then the ratios of corresponding sides must be equal
compare ratios of lengths and widths
rectangles A and B
k = = ← ratio of lengths
k = = ← ratio of widths
scale factors are equivalent, hence rectangle A is a scaled copy of B
rectangles C and B
k = = ← ratio of lengths
k = = ← ratio of width
scale factors (k ) are not equal, hence C is not a scaled copy of B
rectangles A and C
k = = ← ratio of lengths
k = ← ratio of widths
the scale factors are not equal hence A is not a scaled copy of C
I think the answer is 4.472135955, but rounded is 4.5. Sorry if I'm wrong.
Answer: final ≈ 48.91 OR = 48.9125
Explanation:
total price = price b4 tax + tax(price b4 tax)
total = $45.50 + 7.5%($45.50)
= 45.5 + 0.075(45.5)
= 45.5 + 3.4125
= 48.9125
