Doctors measure the visceral fat area (VFA) of four patients using a CT scan to evaluate their risk of developing cardiovascular disease.
The table below shows four different visceral fat area categories:
| Visceral fat area in cm2\text{cm}^2cm2 | Risk category |
|---|---|
| <70< 70<70 | Low |
| 70–9970\text{--}9970–99 | Moderate |
| 100–129100\text{--}129100–129 | High |
| 130 and above130\text{ and above}130 and above | Very High |
The graph below shows the visceral fat area of four patients: A, B, C, and D.
The visceral fat area of patient D is greater than the visceral fat area of patient A.
Calculate how many times greater.
