Two pentagons are similar. The area of one of the pentagons is 9 times
that of the other. Determine the ratios of the lengths of the corresponding
sides and the perimeters of the pentagons.​

Respuesta :

Answer:

The ratios of the lengths of the corresponding  sides of the two pentagons is 3:1

The ratios of the perimeters of the two pentagons is 3:1

Step-by-step explanation:

Let the first pentagon be X and the second pentagon be Y.

Ratio of area of the two pentagons is [tex]\frac{A1}{A2} = \frac{9}{1}[/tex]

Ratio of sides of the pentagon is equal to

[tex]\frac{S1}{S2} = \sqrt{\frac{A1}{A2} }\\=\sqrt{\frac{9}{1} } \\=\frac{3}{1}[/tex]

Ratio of perimeters is equal to ration of sides

Hence,

[tex]\frac{P1}{P2} = \frac{3}{1}[/tex]
