    So, lets find the relationship between area and perimeter between similar figures.

    So when the perimeter was multiplied by 2, how much was the area multiplied by? and, I know this is not your question, I'm showing you an example so you can understand better. :)

    It was multiplied by 4, right?

    yes, and if you see the relationship, it was actually multiplied by \((2)^2\) So for your question now.

    So Triangle ABC is bigger than Triangle DEF The perimeter of ABC is perimeter of DEF multiplied by 5 The area of ABC is area of DEF multiplied by __

    From the example, we learned that when we multiply the perimeter by x, then the area is multiplied by x^2

    Wait, I don't understand. I put the answer as 4..? or.. am I not understanding this?

    The answer is 4. :)

    Because the relationship between the area in this question would be 25. And 100/25 = 4
