The Formula Of Triangle
Triangle is a form made of three sides in the form of a straight line and three angles.
This time we will share knowledge about the formula of area and circumference of triangle. the following is the formula of the area and circumference of the triangle:
Formula:
Example:
What is the area of the image bellow ?
Answer:
Pedestal = 5cm
Height = 2cm
Triangle area = 1/2 (Pedestal x Height)
Triangle area = 1/2 (5cm x 2cm)
Triangle area = 1/2 (10cm2)
Triangle area = 5cm2
So the area of the image is 5cm2.
Formula:
Information:
a, b, and c = side of triangle
Example:
What is the area of the image bellow?
Answer:
a = 3cm
b = 3cm
c = 4cm
Triangle circumference = a + b + c
Triangle circumference = 3cm + 3cm + 4cm
Triangle circumference = 10cm
So the circumference of the image is 10cm.

This time we will share knowledge about the formula of area and circumference of triangle. the following is the formula of the area and circumference of the triangle:
1. Triangle Area
Triangle area = 1/2 (Pedestal x Height)
Example:
What is the area of the image bellow ?
Answer:
Pedestal = 5cm
Height = 2cm
Triangle area = 1/2 (Pedestal x Height)
Triangle area = 1/2 (5cm x 2cm)
Triangle area = 1/2 (10cm2)
Triangle area = 5cm2
So the area of the image is 5cm2.
2. Triangle Circumference
Triangle circumference = a + b + c
Information:
a, b, and c = side of triangle
Example:
What is the area of the image bellow?
a = 3cm
b = 3cm
c = 4cm
Triangle circumference = a + b + c
Triangle circumference = 3cm + 3cm + 4cm
Triangle circumference = 10cm
So the circumference of the image is 10cm.
