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.

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.

Drag Racing Integers

Drag Car with chute
Image Source: http://graphics8.nytimes.com

The positive force of a drag racing car at full speed is far too big to be
overcome by normal braking. It is like an integer sum of 1000 and -300.
There is still 700 of forward force to cancel out before the car can reach zero and stop moving.

Sorry Picture Not Found

To produce the required additional negative force, parachutes are used.
The math calculation is critical. Not enough parachutes and the car goes off
the end of the track. Too many parachutes used, and the car cannot take the strain, nor can the driver endure the G forces exerted on his or her body.

Here is a YouTube video which shows in slow motion, parachutes being deployed on Drag Racing Cars.

[youtube=http://www.youtube.com/watch?v=mJMe7DEj3ZY&w=540&h=435]

Here is a video which shows what happens when the parachutes fail to deploy.

[youtube=http://www.youtube.com/watch?v=BLPHBj8o16k&w=540&h=435]

There are also some very cleverly balanced Positive and Negative forces involved with the amazing energy absorption by the safety nets.

So hopefully Integers won’t be so much of a DRAG in mathematics, now that you know a bit about the POSITIVE contribution that directed numbers make to drag car racing.
