The formula is: Area = w × h. w = width. h = height. We know w = 5 and h = 3, so: Area = 5 × 3 = 15.

The formula for the area of a triangle is height x π x (radius / 2)2, where (radius / 2) is the radius of the base (d = 2 x r), so another way to write it is height x π x radius2.
What are Geometry Formulas? The formulas used for finding dimensions, perimeter, area, surface area, volume, etc. of 2D and 3D geometric shapes are known as geometry formulas. 2D shapes consist of flat shapes like squares, circles, and triangles, etc., and cube, cuboid, sphere, cylinder, cone, etc are some examples of 3D shapes.
Here are some solved examples based on the formulas of the area as well as perimeter of different shapes. Example 1: If the radius of a circle is 21cm. Find its area and circumference. Solution: Given, radius = 21cm. Therefore, Area = π × r 2. A = 22/7 × 21 × 21. A = 1386 sq.cm. Circumference, C = 2πr C = 2 x 22/7 x 21 = 132 cm. Example 2:
21 lip 2022 · The formula for the perimeter of a rectangle is often written as \(P = 2l + 2w\), where \(l\) is the length of the rectangle and \(w\) is the width of the rectangle. Area of Parallelograms. The area of a two-dimensional figure describes the amount of surface the shape covers.
