Hello!
First, let's analyze the figures 1 and 2:
• One side of figure 1 is 6, while the same side in figure 2 is 9.
Knowing it we can calculate the ratio, using the formula:
[tex]\frac{\text{ side of figure 2}}{\text{ side of figure 1}}[/tex]
Let's replace them with the values:
[tex]\frac{9}{6}=1.5[/tex]
So, it means that figure 2 is 1.5 times bigger than figure 1.
Let's complete the spaces:
• If the perimeter of 1 is 20, the ,perimeter of 2 will be ,20 * 1.5 = 30,.
,
• If the area of 2 is 45, the, area of 1 will be ,45 / 1.5 = 30,.
