The Figures Are Similar Find X The Ratio Of The Perimeters Is 57 class=

Answer :

Answer:

x = 16.8

Step-by-step explanation:

The ratio of corresponding sides is equivalent to the ratio of the perimeters.

Then using proportion

[tex]\frac{12}{x}[/tex] = [tex]\frac{5}{7}[/tex] ( cross- multiply )

5x = 84 ( divide both sides by 5 )

x = 16.8
