# How to Calculate and Solve for the Area, Base and Height of a Triangle | The Calculator Encyclopedia

**Last Updated on February 15, 2024**

To calculate the area of a triangle two essential parameters are required which are the **base of the triangle** and the **height of the triangle**.

The formula for calculating the area of a triangle is:

A = 0.5bh

Where:

A = Area of a Triangle

b = Base of a Triangle

h = Height of a Triangle

Let’s solve an example:

Given that the base of a triangle is 12 cm and the height of the triangle is 4 cm. Find the area of the triangle.

This implies that:

b = Base of the Triangle = 12 cm

h = Height of the Triangle = 4 cm

A = 0.5bh

A = 0.5(12)(4)

Then, A = 0.5(48)

A = 24

Therefore, the **area of the triangle** is **24 cm ^{2}**

**How to Calculate the Base of a Triangle when the Area and Height of the Triangle is Given**

The formula is:

b = ^{2A} / _{h}

Where:

b = Base of the Triangle

A = Area of the Triangle

h = Height of the Triangle

Let’s take an example:

Find the base of a triangle when the height and area of the triangle is 12 cm and 40 cm^{2} respectively.

This implies that:

A = Area of the Triangle = 40 cm^{2}

h = Height of the Triangle = 12 cm

b = ^{2(40)} / _{12}

b = ^{80} / _{12}

So, b = 6.667

Therefore, the **base of the triangle** is **6.667 cm**.

**How to Calculate the Height of a Triangle when the Area and Base of the Triangle is Given**

The formula is:

h = ^{2A} / _{b}

Where:

h = Height of the Triangle

A = Area of the Triangle

b = Base of the Triangle

Let’s take an example:

Find the height of a triangle when the base and area of the triangle is 20 cm and 80 cm^{2} respectively.

This implies that:

A = Area of the Triangle = 80 cm^{2}

b = Base of the Triangle = 20 cm

h = ^{2(80)} / _{20}

h = ^{160} / _{20}

So, h = 8

Therefore, the **height of the triangle** is **8 cm**.
