Question

What is the difference between area and perimeter of a two-dimension figure? What is the difference in the area formulas for a parallelogram and triangle

Answer 1

The perimeter is a measure of the distance around the shape. This means that to find the perimeter we usually are going to add the lenghts of the sides of the figure (the circle is an exception to that rule since this is a curve figure).

The are is a measure of the space inside the figure. This means that to find the area we usually are going to multiply the lenghts of the sides of the figure to get the area.

Now the area of a triangle is given as:

$A=\frac{1}{2}bh$

whereas the area of a paralelogram is given by:

$A=bh$

From this we notice that the area of the triangle is half the area of a parallelogram.
