Example 2: If we need to find the length of the boundary of a square park, we must find its perimeter.There are many such things, where we can find the perimeter.Area and PerimeterThe area is the region or surface bounded by the shape of an object. The total space covered by a ...
Since the area of a rectangle is the product of the length and width, it is measured in square units, like, square meters (m2), square inches (in2) and so on. Perimeter of a Rectangle The perimeter of a rectangle is the sum of the length of its four sides. Let’s find the f...
From the formula A=rs, where A is the area of a triangle,r is its inradius, and s is the semiperimeter, we can find that r=2032/2=54. It is known that in a right triangle, r=s−h, where h is the hypotenuse, so h=16−54=594. From the problem, we know that a+b+c...

Why is it called pi? It wasn’t given its name until 1706, when Welsh mathematician William Jones began using the Greek symbol for the number. Why that letter? It’s the first Greek letter in the words “periphery” and “perimeter,” and pi is the ratio of a circle’s peri...
Area and perimeter of a square:A square is a geometric shape with four sides. All the sides are equal to each other. On top of that, all the interior angles are 90 degrees. The perimeter of square= Sum of all sides = 4 times the length ...
Area measures the surface space within a boundary, expressed in square units, while perimeter defines the total length of the boundary of a shape.
