Measurement Formulas 1

Image Source: http://bridge.tm.mbs.ac.uk In this post we have used Adobe Fireworks to make mini posters of a number of Measurement Formulas for length, area, and volume. We have not included all shapes, and we have not covered Surface Area. We plan to do these in a future post. The information presented here is invaluable to students revising Measurement. Perimeter Perimeter is the total length around the OUTSIDE of any shape. It is given the special name of “Circumference” when dealing with circular shapes.

We can work out its area using Base x Height, but we can also work out the same area by multiplying the two internal diagonals together, and dividing by 2.

Area of a Kite A Kite is a similar shape to a Rhombus, and its area is obtained by multiplying together its diagonals.
