# How do you find the area of base x height?

## How do you find the area of base x height?

To calculate the area of a triangle, we multiply the base times the height and divide by 2. If you are given the area, follow the steps backwards. You will multiply by 2 and divide by the given length.

### What formula uses base area and height?

The formula for the volume of a prism is V=Bh , where B is the base area and h is the height. The base of the prism is a rectangle. The length of the rectangle is 9 cm and the width is 7 cm.

#### What is triangular area?

The area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle.

How volume is area x height?

Volume of Prisms and Cylinders Effectively, for cylinders and prisms, the volume is the area of one side multiplied by the depth or height of the shape. The basic formula for volume of prisms and cylinders is therefore: Area of the end shape × the height/depth of the prism/cylinder.

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.

## How do you calculate the area of the base?

Calculation of Base Area of Cylinder

1. Step 1: Calculate the radius of the base of the cylinder.
2. Step 2: Find the square of the radius.
3. Step 3: Find out the product of the square of its radius to π.
4. Step 4: The answer is in square units of the unit of the length radius.

### How do u calculate the area of a trapezium?

The area of a trapezium is computed with the following formula: Area = 1 2 × Sum of parallel sides × Distance between them .

#### What is the formula to find the area of an area?

formula to find area = (1/2) b h = (1/2) x Base x Height

Why is the area of a triangle 1/2 base times height?

And this can be ANY triangle. The reason is the area is the base times the height all divided by 2. But for other triangles we need to calculate the height which isn’t evident. The sine of C times length or side a actually gives the height and so the area is 1/2 base times the height.

How do you find the area of a triangle with base 18?

Find the area of a triangle having the base b = 18 & height h = 12 cm? Solution : The given values. base b = 18 cm. height h = 12 cm. Step by step calculation. formula to find area = (1/2) b h. = (1/2) x Base x Height. substitute the values.

## What is the formula for area of any none right angled triangle?

The sine of C times length or side a actually gives the height and so the area is 1/2 base times the height. Hence 1/2 times absinC is the formula for area of any none right angled triangle. We start at angle 0 where the projection on the y axis is zero and so sine of zero is 0.
