## How do you find the base if you have the area and height?

The best known and the simplest formula, which almost everybody remembers from school is: area = 0.5 * b * h , where b is the length of the base of the triangle, and h is the height/altitude of the triangle.

## How do you calculate the base?

For example, a circle with a radius of 3 cm would yield an equation like this: area = π3^2. Simply the equation to determine the area of the base. π3^2 simplifies to 3.14(9), or 28.26. Therefore the area of the circular base is 28.26 cm^2.

**What is the formula of area of base?**

Rectangular Bases The area of a rectangle is equal to its length, l, multiplied by its width, w: A = l x w. Given a pyramid whose base is 10 inches long and 15 inches wide, find area as follows: A = 10 inches x 15 inches = 150 square inches.

### What is the area of a triangle with base b and height?

To be noted, the base and height of the triangle are perpendicular to each other. The unit of area is measured in square units (m2, cm2). Example: What is the area of a triangle with base b = 3 cm and height h = 4 cm? Area of a Triangle, A = 1/2 × b × h = 1/2 × 4 cm × 3 cm = 2 cm × 3 cm = 6 cm 2.

### How do you find the area of a right triangle?

In this case, we have to take a few more steps to solving for the area of a right triangle. So, let’s go through the process of determining the base and height of a right triangle so we can perform the formula A = ½ base × height. We use the pythagorean theorem to determine the side lengths of a right triangle.

**How do you find the altitude of triangle ABC?**

The altitude of triangle ABC was created by forming the line labeled h (height). Since ACD is a right triangle, we can find it’s area with the equation A = ½ base × height. We can also determine the area of the larger triangle ABD using this equation. To find the area of obtuse triangle ABC, we must then subtract the area of ACD from ABD:

#### What units are used to measure the area of a triangle?

It is applicable to all types of triangles, whether it is scalene, isosceles or equilateral. To be noted, the base and height of the triangle are perpendicular to each other. The unit of area is measured in square units (m2, cm2).
