# What is the ratio of the area of ABC to the area of ABD?

The area of a right triangle is given by the formula: 1/2 × Base × Height

## Answer: The ratio of the area of ABC to the area of ABD is 1:5

We will use the formula of the area of a right triangle to find the required ratio.

## Explanation:

Area of Triangle ABC = 1/2 × Base × Height

= 1/2 × 3 units × 4 units

= 6 square units

Area of Triangle ABD = 1/2 × Base × Height

= 1/2 × 5 units × 12 units

= 30 square units

Area of Triangle ABC / Area of Triangle ABD = 6 square units / 30 square units = 1/5
