Area and Perimeter of Triangles & Quadrilaterals
5 4 3 2 1 Area and Perimeter of Triangles & Quadrilaterals I understand and can explain the difference between area and perimeter. I can find the area and perimeter of shapes by counting squares. I can find the area of rectangles and squares using a formula. I can find the area of compound shapes, triangles, parallelograms, trapeziums and kites. I can solve area and perimeter problems by forming and solving equations.
