Introduction

In geometry, a right triangle is a triangle with one angle that is 90 degrees. The area of a right triangle can be calculated using the formula: Area = (base × height) / 2. In this article, we will explore how to find the area of a right triangle using this formula and provide a step-by-step guide on how to do it.

Understanding the Formula

The formula for finding the area of a right triangle is: Area = (base × height) / 2. This formula is derived from the fact that the area of a triangle is equal to half the product of its base and height. In the case of a right triangle, the base and height are the two sides that form the right angle.

Identifying the Base and Height

To find the area of a right triangle, we need to identify the base and height of the triangle. The base is the side that is opposite the right angle, and the height is the side that is perpendicular to the base. In the given problem, the base of the triangle is 9 inches and the height is 8 inches.

Calculating the Area

Now that we have identified the base and height of the triangle, we can calculate the area using the formula: Area = (base × height) / 2. Plugging in the values, we get:

Area = (9 × 8) / 2 Area = 72 / 2 Area = 36

However, this is not the correct answer. We need to consider the fact that the triangle is not drawn to scale. This means that the actual dimensions of the triangle may be different from the given values. To find the correct answer, we need to use the given options and calculate the area using the formula.
