Answer:
These two figures are similar because 5/3 equals 15/9.
Step-by-step explanation:
If two figures are similar, their corresponding sides are proportional.
This means comparing the sides, we get equivalent ratios.
The ratio of the sides of the smaller rectangle is 5/3. The ratio of the sides of the larger rectangle is 15/9.
5/3(3/3) = 15/9; this means these are equivalent ratios, which means the corresponding sides are proportional and the figures are similar.
The answer is the bottom right answer.
The figures are similar because the lengths of corresponding pairs of sides are in the same ratio.
a2+b2=25
or, (a+b)^2-2ab=25
or, (7)^2-2ab=25 [a+b=7]
or, 49-25=2ab
or, 24/2=an
•°• ab=12....
