It helps you in real life situations such as how much fencing to put around your yard.
Well, in math you solve the perimeter of circles and such, and learn understanding of them to help you with circles in real life.
The perimeter of the square is 96.
There are an infinite number of shapes with an area of 16 square centimetres. The one with the smallest perimeter is a circle of radius 2.2568 cm (to 4 dp). Such a circle will have a perimeter of 14.1796 cm. This value for the perimeter can be increased by changing the circle into an ellipse: making the ellipse flatter and longer (increasing its eccentricity) so that the perimeter increases without changing the area. There is no upper bound to the perimeter. This can also be done for quadrilaterals, with the smallest one being a 4cm x 4cm square. But you could have a rectangle with sides 0.4 cm and 40 cm and a perimeter of 80.8 or 0.04 cm and 400 cm and a perimeter of 800.08 cm or 0.004 cm and 4000 cm and a perimeter of 8000.008 cm and so on - without limit. Or you could have triangles, or polygons with 5 or more sides. The important point is that area does not determine the perimeter.
It is important to measure area and perimeter or perimeter and area same thing any ways it's important because if you don't you will never find your answer

There is no reason for the perimeter of a triangle to have any relation to the perimeter of an unrelated rectangle!
the ratio of the perimeter of triangle ABC to the perimeter of triangle JKL is 2:1. what is the perimeter of triangle JKL?
Semi-perimeter means half the perimeter. Calculate the perimeter, then divide that by 2 to get the semi-perimeter.
