Question

The figures are similar. Give the ratio of the perimeters and the ratio of the areas of the first figure to the second. The figures are not drawn to scale.

Answer 1

Answer:
Ratio of the perimeters: 7/2
Ratio of the areas: 49/4

Explanation:
The ratio of the perimeters is the same as the ratio of the sides, so 28/8 reduces down to 7/2

The ratio of the area is the same as the ratio of the perimeters (or sides), only each number is squared. So, 28^2 over 8^2 is 784/64, which reduces down to 49/4 (which is 7 squared over 2 squared; you can also use the reduced ratio of the sides)
