The term perimeter refers to the coverage of the length of a figure from the outside. At the same time, the area is known as the object's surface. For different sets of figures, there are different formulas.
Here, all different figures consist of different perimeters and areas. These are:
The perimeter of the square is 4a, and its area is a^2.
Note: In the formula, a is the side of a square.
The rectangle's perimeter is 2 (l + b), and its area equals l x b.
Note: In the formula, l & b are the length and breadth of the square.
The circle's perimeter is 2πr, and its area is equal to πr^2.
Note: r is the radius of a circle, i.e., r = 2d (d = diameter)
The triangle's area is equal to ½ x b x h.
The parallelogram's area is b x h.
To get the area and perimeter of a closed figure, we have to consider all figures in one unit. Only then do we have to apply the formula to get the results.
