Measurement Formulas 1

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 is the total length around the OUTSIDE of any shape. It is given the special name of “Circumference” when dealing with circular shapes.

The following formulas give the Areas of common shapes such as Squares, Rectangles, Parallelograms, Triangles, Trapeziums, and Circles.

Area of a Rhombus

A Rhombus is a Parallelogram that has all four sides equal. 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.

Answers to Rhombus Questions:
Q1. 418 sq cm, 41600 sq mm, 0.0006 sq m.
Q2. 91 sq cm
Q3. (1000×2) / 10 = 200mm.
Q4. (120×2) / 30 = 8m.

Area of a Kite

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

    There is a mistake on circumference. Should it not be Pi x 2R NOT 2Pi x R
