Area is calculated by multiplying the length of a shape by its width. In this case, we could work out the area of this rectangle even if it wasn't on squared paper, just by working out 5cm x 5cm = 25cm² (the shape is not drawn to scale).

Pythagoras therom - Maths
Pythagoras theorem - a theorem attributed to Pythagoras that the square on the hypotenuse of a right-angled triangle is equal in area to the sum of the squares on the other two sides.
Pythagoras, who is he? Where did he live and what did he do?Pythagoras was a Greek philosopher and mathematician.He lived in Metapontum village and Cortona. He made important developments in mathematics, astronomy, and the theory of music.
Triangle facts - Maths
Triangle facts - There are always going to be 3 sides.
- All angles add up to 180 degrees
-A triangle can always be split into 2 right angles no matter how it is constructed
Different types of triangles - Equilateral triangle = all sides are equal
- Obtuse = greater than 90 degrees
-Acute = Less than 90 degrees
- Scalene = None of the sides are the same
-Right angle triangle = one angle is 90 degrees
-Isosceles = 2 sides are always equal
MATHS - Volume
What is volume - In math, volume is the amount of space in a certain 3D object. For instance, a fish tank has 3 feet in length, 1 foot in width and two feet in height. To find the volume, you multiply length times width times height, which is 3x1x2, which equals six. So the volume of the fish tank is 6 cubic feet. formula for volume - Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.
