We are surrounded by so many 2-D shapes: circle, triangle, square, rectangle, parallelogram, and trapezium. You can draw all of these shapes on your paper. Every shape is different and unique, so its area is also calculated differently. To find the area, first, identify the shape. Then, use the appropriate formula from th See more

Decide math equation

Math is all about finding the right answer, and sometimes that means deciding which equation to use.

In this example, Area= lw = (5)(3) = 15m2 A r e a = l w = ( 5) ( 3) = 15 m 2. Triangles. The area of a triangle is given by: Area= 1 2bh A r e a = 1 2 b h. where b is the base and h is the height

Example: The circle has a radius of 2.1 meters: The formula is: Area = π × r2 Where: π = the number pi (3.1416) r = radius The radius is 2.1m, so: Area = 3.1416 × (2.1m)2 = 3.1416 × (2.1m × 2.1m) = 13.854 m2 So the circle has

Let's break the area into two parts: Part A is a square: Area of A = a 2 = 20m × 20m = 400m 2. Part B is a triangle. Viewed sideways it has a base of 20m and a height of 14m. Area of B = ½b × h = ½ × 20m × 14m = 140m 2. So the total area
