Measuring Area

Use formulae for regular figures e.g. cylinder, square pyramid et.c.
Square = length x length
Rectangle = Length x breath
Triangle = ½ x base x height
Circle = πr(square)

For irregular figures:
• Use estimation.
• Done by dividing the figure into small squares.
• The area of each square has to be first defined.
• If more than half the area of the square is occupied, it will be taken as part of the
reading.
• If less than half the area of the square is occupied, it will not be taken as part of the
reading.
• The smaller the squares, the greater the accuracy.
