Question

There are two similar shapes. The smaller shape has a perimiter of 25 with an area of 17. What is the area of the larger shape if it has a perimeter of 100?

Answer 1

Answer: 68

Explanation:

The ratio of the perimeter of the smaller shape to the larger shape is:

25:100 or 1:4

Since the shapes are similar, the ratio of the area is going to be the same as the perimeter.

1:4 = 17: 68
