In these lessons, we have compiled. a table of area formulas and perimeter formulas used to calculate the area and perimeter of two-dimensional geometrical shapes: square, rectangle, parallelogram, trapezoid (trapezium), triangle, rhombus, kite, regular polygon, circle, and ellipse. a more detailed explanation (in text and video) of each area formula If the height and base are given, then here's a simple code: 10 PRINT Area of a Regular Triangle 20 INPUT Enter base: ; b 30 INPUT Enter height: ; h 40 LET A = (0.5) * b * h 50 PRINT Area = ; A Sample Output (with test values)

Area of Triangle =. Now, we can easily derive this formula using a small diagram shown below. Suppose, we have a. as shown in the diagram and we want to find its area. Let the coordinates of vertices are (x1, y1), (x2, y2) and (x3, y3). We draw perpendiculars AP, BQ and CR to x-axis The area is given by:where p is half the perimeter, or. The perimeter of the isosceles triangle is relatively simple to calculate, as shown below. For an isosceles triangle, along with two sides, two angles are also equal in measure. If the angle of the two triangles is the same then, it will be called an equiangular triangle. We always think from the examination point of view before preparing. Practice Problems Using Herons Formula - Practice questions. Question 1 : The perimeter of a triangular plot is 600 m. If the sides are in the ratio 5 : 12 : 13, then find the area of the plot. Solution : The sides of triangle be 5x, 12x and 13x. Perimeter of triangular plot = 600. 5x + 12x + 13x = 600. 30x = 600
