PERIMETER AND AREA OF A SHAPE PART I BS 6

Perimeter refers to the total sum of the circumference around an object. And area is the extent or the measurement of the surface area.

PERIMETER OF SIMPLE SHAPES

FIGURE	FORMULA	NOMENCLATURE
	Perimeter= a+b+c Area=½bh	a,b,c: sides Base, height
	Perimeter = 4a and area= a²	a=side
	PERIMETER 2b + 2h Area= we will come back same	b = base H=height
	Perimeter is 2πr Areaπr²	r=rasiums

PERIMETER OF A TRIANGLE

From the notes above, we got to know that, when finding the perimeter of a triangle, add all the sides of the triangle. Therefore with this, let's solve an example;

SAMPLE 1: find the perimeter of the triangle.

SOLUTION 

 3cm + 5cm + 4cm

=12cm

END OF LESSON EXERCISE

1. If the triangle below is an equilateral triangle, find the perimeter of the triangle below.

2. Find the perimeter of the triangle.
