WebNov 22, 2024 · Area and perimeter of a regular pentagon Area A of a regular pentagon can be calculated from the formula: area = a² × √ (25 + 10√5) / 4, where a is a side of a regular pentagon. Also, you can find the area having the circumscribed circle radius: area = 5R² × √ [ (5 + √5)/2] / 4, where R is the circumcircle radius. WebMar 8, 2024 · The perimeter of a parallelogram is the total distance enclosed by its boundary. Since the parallelogram is a type of quadrilateral, thus it has four sides. The perimeter of the parallelogram will be equal to the sum of all these four sides. Geometry is a branch of mathematics that deals with the study of different geometrical shapes.

WebNov 10, 2024 · As we know that. Formula for the perimeter of an equilateral triangle. Perimeter of an equilateral triangle = Side + Side + Side. Perimeter of an equilateral triangle = 3 × a. where a is side of an equilateral triangle. Perimeter of an equilateral triangle = 3 × 23. Perimeter of an equilateral triangle = 69 cm. WebIf the triangle has a very long leg L and a short leg of length x, the area is 1 2 x L, so L = 2 x. The perimeter is then x + L + x 2 + L 2 ≈ 2 L which can be as large as you like. Let l, b be the side lengths. Then, You should be able to simplify this expression. If the base is b and the height is c then the area is b c / 2 and the perimeter ...
