The perimeter of a rectangle is x units. If the length is z more than the width, find the area of the rectangle.
The truth is, they're not that hard! Once this is changed into algebraic form it becomes a simple algebra problem. I'll show a few examples of such problems:
Example 1:
The perimeter of a rectangle is 68. If the length is 4 more than twice the width, find the dimensions and the area of a rectangle.

Gravity acceleration at the Earth surface is 9.81 m%2Fs%5E2.
How much is this in ft%2Fs%5E2? In in%2Fs%5E2?
Solution
1 ft = 0.3048 m (see, for example, the units converter under this topic, or any appropriate handbook, textbook, or the Internet web-site).
So, 1 m = 1/0.3048 ft = 3.2808 ft = 12*3.2808 in = 39.37 in.
Therefore, 9.81 m%2Fs%5E2 = 9.81 * 3.2808 ft%2Fs%5E2 = 32.19 ft%2Fs%5E2.
Further, because 1 ft = 12 in, we have
9.81 m%2Fs%5E2 = 32.19 ft%2Fs%5E2 ...MathFri, 27 Mar 2015 20:03:28 GMThttp://kingeducation.forumotion.com/t4-units-conversion-examples#4HOW TO multiply negativeshttp://kingeducation.forumotion.com/t3-how-to-multiply-negativeshttp://kingeducation.forumotion.com/t3-how-to-multiply-negativesAdminThe rule of how to multiply negatives is simple:
To multiply a negative number by any number, take the (positive) opposite of the negative number and multiply it by the other number, and take the opposite of that
Negative by positive number
For a case where a negative number is multiplied by a positive, the rule above can be restated as: take the positive number, and the negative WITHOUT the minus sign, multiply them and add the inus sign to the product.
Example: multiply 5 and ...MathFri, 27 Mar 2015 20:02:15 GMThttp://kingeducation.forumotion.com/t3-how-to-multiply-negatives#3Join King Educationhttp://kingeducation.forumotion.com/t2-join-king-educationhttp://kingeducation.forumotion.com/t2-join-king-educationAdminJoin Kinge Its good!
