Question

Find the values of the ratios

Answer 1

Answer:

• perimeter: 5/8
• area: 25/64

Step-by-step explanation:

You want the ratios (red to blue), of perimeter and area, given that corresponding sides have the ratio red to blue = 5 to 8.

Perimeter ratio

The ratio of perimeters is the ratio of corresponding side lengths:

  red to blue = 5 / 8

Area ratio

The ratio of areas is the square of the ratio of corresponding side lengths:

  red to blue = (5 to 8)² = 25 / 64
