    Area is a way to measure the size of flat surfaces or 2D shapes. A 2D shape is larger than another if it has a greater area.

    Area is the space occupied by a figure or a shape.

    Definition of Area

     

     In rectangles and in squares, a simple calculation of length times width will give the number of square units. The square units could be inches, centimeters, yards etc. or whatever the requested unit of measure asks for.

    To put it simply, area is the sum of unit squares.

    Area = length times width. (i.e., A = L x W)

    So if it's a shape like a square or rectangle, measure how long the sides are and multiply them together to get the area.

    Area is the total space occupied by a figure in a space. The unit of area is represented by the power of two that is it is found by multiplying the sides. For a square its area is length*breadth.

Simplify expressions with surds into the form a + b3

Be warned this topic is Chuck Norris hard. Make sure you've done the related topics below before you try and get your head round this one...

---------------------------------

So if you put a square root sign around a number that is not a square number, then what you have written is a surd.

e.g. √10 is a surd, because 10 is not a square number. √9 is not a surd, because 9 is a square number, so you can write √9= 3

Even if the number under the square root sign is not a square number, it can still be simplified.

Write the starting number as a product of two new numbers, where one of them is a square number (e.g. 45 -> 9 x 5).  Take the root of the square number, and write it outside of the root sign

e.g. √45 = √(9×5)=3√5
