# How to work out area of a triangle?

#### Understand the Problem

The question is asking for the formula or method to calculate the area of a triangle. It implies the need to understand the basic geometric principles involved in finding the area based on different variables like base and height.

A = \frac{1}{2} imes b imes h

To find the area of a triangle, use the formula: $A = \frac{1}{2} imes b imes h$, where $b$ is the base and $h$ is the height.

#### Steps to Solve

1. Identify the base and height of the triangle

To find the area, you should know the base (b) and the height (h) of the triangle. The base is any one of the sides of the triangle, and the height is the perpendicular distance from this base to the opposite vertex.

1. Use the area formula

The formula to calculate the area of a triangle is: $$A = \frac{1}{2} imes b imes h$$ where $A$ is the area, $b$ is the base, and $h$ is the height.

1. Insert the base and height into the formula

Plug in the values for the base and height into the formula. For instance, if the base is 5 units and the height is 4 units: $$A = \frac{1}{2} imes 5 imes 4$$

1. Calculate the area

Perform the multiplication and division: $$A = \frac{1}{2} imes 20 = 10$$ So, the area of the triangle is 10 square units.

To find the area of a triangle, use the formula: $A = \frac{1}{2} imes b imes h$, where $b$ is the base and $h$ is the height.
