What is a Ratio?
A ratio shows us the number of times a number contains another number.
As it is given that the length of the bottom side of the pentagon is x centimeters while the length of the left side is 7 centimeters. Also for the larger pentagon, the length of the bottom side is 7 cm, while the length of the left side is 15 cm. Therefore, the ratio of the bottom side and the left side will be,
[tex]\dfrac{\text{Lenght of bottom}}{\text{Length of left side}} = \dfrac{x}{7} = \dfrac{7}{15}\\\\x = \dfrac{7 \times 7}{15} = \dfrac{49}{15} = 3.26667 \approx 3.3[/tex]
Thus, the value of x is 3.3.
