Basic Geometry Formulas Area Perimeter Volume Perimeter = a b c. to find out the triangle's area, you will need only the length of the base (b) and the height (h), which is measured from the base to the peak of the triangle. this formula works for any triangle, no matter if the sides are equal or not. area = 1 2 bh. 10. Area = π × r2 example: rπ = pi = 3.14 r = radius = 5cm area = 3.14 × 52 = 3.14 × 5 × 5 = 78.5cm2 r a surface area = 6 × a2 example: a = 5cm surface area = 150cm surface area = 2 × ba la example: ba = base area = 20cm2 la = lateral area (all sides) = 60cm2 surface area = 2 × 20 60 = 100cm2 surface area = ba la example: ba = base. Find the formulas for calculating the area, surface area and volume of common shapes in geometry. download the pdf or see the graphic and definitions on this page. 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. the basic geometry formulas are given as.

Here are the most important and useful area formulas for sixteen geometric shapes: square area formula: a = a². rectangle area formula: a = a × b. triangle area formulas: a = b × h 2 or. a = 0.5 × a × b × sin(γ) or. a = 0.25 × √( (a b c) × ( a b c) × (a b c) × (a b c) ) or. Area of the base x height triangle: s 1 s 2 s 3 triangular prism: area of the base x height square: 4s s 2: right prisms perimeter of the base x height: lateral surface area 2 (area of the base) area of the base x height: circle cylinder: area of the lateral space (rectangle) lateral surface area 2 (area of the base) area of the base x.
