How Do You Write A Program That Calculates The Area Of A Triangle? - Fixanswer

To calculate the area of a triangle,

multiply the height by the width (this is also known as the ‘base’) then divide by 2

. Find the area of a triangle where height = 5 cm and width = 8 cm. A triangle is always half the area of a rectangle with the same height and width. JavaScript is required to view this activity.

How do you find the area of a triangle in C++ program?

Algorithm. Take input of the three sides of the triangle from the user and store them in the variables a, b and c. Declare a

variable area of float type

and calculate and store area of the triangle in it using s and the given formula. Print area.

How do you write a program to find the area of a triangle?

To calculate the area of a triangle we will use

the formula Area = (b * h)/2

. At last, print the area of the triangle to get the output.

What is area formula?

Table 2. Area Formulas	Shape Formula Variables	Square A =s2 s is the length of the side of the square.	Rectangle A=LW L and W are the lengths of the rectangle’s sides (length and width).	Triangle A=12bh b and h are the base and height

How do we calculate area?

We measure area in square units : cm2 or m2. Area is

calculated by multiplying the length of a shape by its width

. In this case, we could work out the area of this rectangle even if it wasn’t on squared paper, just by working out 5cm x 5cm = 25cm2 (the shape is not drawn to scale).

What is the first step in finding the area of the triangle?

To find the area of a triangle,

multiply the base by the height, and then divide by 2

. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles. For example, in the diagram to the left, the area of each triangle is equal to one-half the area of the parallelogram.

What are the examples of algorithm?

Algorithms are all around us. Common examples include:

the recipe for baking a cake

, the method we use to solve a long division problem, the process of doing laundry, and the functionality of a search engine are all examples of an algorithm.

How do you use the algorithm to find the area of a rectangle?

Define the width of the rectangle.
Define the Height of the rectangle.
Define Area of the rectangle.
Calculate the area of the rectangle by multiplying the width and height of the rectangle.
Assign the area of the rectangle to the area variable.
print the area of the rectangle.

What command is used to find the area of triangle?

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 do you write a simple interest program?

Simple Interest = (P × R × T)/100.
where P = Principal Amount, R = Rate per Annum, T = Time (years)

What is triangular area?

A triangle is a polygon with three sides. … So, 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

. Example: Find the area of the triangle. 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.

What are the formulas for area and perimeter?

Figures Area Formula Variables	Area of Rectangle Area = l × w l = length w = width	Area of Square Area = a ² a = sides of the square	Area of a Triangle Area = 1/2 b×h b = base h = height	Area of a Circle Area = πr ² r = radius of the circle

What is the area of this shape?

Shape Area of Shapes – Formula	Rectangle Area of a rectangle = length × width = l × w square units	Circle Area of a circle = π r ² square units	Triangle Area of a triangle =12×b×h 1 2 × b × h square units	Parallelogram Area of a parallelogram = base × height = b × h square units

What is the formula to calculate area of land?

Multiplying length by width gives you the area, or the space inside the boundary of your property. Acreage is simply one measure of area. An easy way to remember the formula for area is

A (area) = L (length) x W (width)

, which is the exact calculation done in this step.
