Establish the formulas for areas of rectangles, triangles and parallelograms and use these in problem solving (ACMMG159)
Outcomes
-
Develop and use the formulas to find the areas of rectangles and squares:
Area of a rectangle = lb where l is the length and b is the breadth (or width) of the rectangle
Area of square = s squared where s is the side length of the square
Examples
-
Find the areas of simple composite figures that may be dissected into rectangles, squares, parallelograms and triangles
