The perimeter is the distance around a given two-dimensional object. Thw word perimeter is a Greekroot meaning measure around, or literally "around measure." Perimeter can be calculated for any two dimensional object, with the right formula.
Are is a physical quantity expressing the size of a part of a surface. The term can also be used in a non-mathematical context to be mean "vicinty."

When you have a 2D figure like a square, the perimeter is the total length of the sides of the square.
To get perimeter, you basically add all the sides.
Same applies for triangle, parallelogram, rhombus, rectangle, trapezium.
In a circle the perimeter is the length of the circumference.
To get the circumference, you use the formula 2*pi*r [ r= radius, pi = 3.14]
area is the space enclosed within the figure. In square , the space within the four sides is the area. To find area, you have to use different formula for different figures.
Square: L^2 [L is side]
Rectangle: L*B [ L= Length, B= Breadth]
Circle : pi * r^2 [ r= radius, pi = 3.14]
triangle: 1/2 * base * altitude

perimeter is like how long the fence is around your yard, area is like how much yard you have. You find area by multiplying the width and the length, and you find the perimeter by adding all the sides
