Learning Intention To develop a single formula for the area of ANY rhombus and Kite. Use the formula to solve problems. Rhombus and Kite Area

Area of a Rhombus D d This part of the rhombus is half of the small rectangle.

Area of a Kite D d Exactly the same process as the rhombus

Rhombus and Kite Area Example 1 : Find the area of the shapes. 5cm 2cm 9cm 4cm

Now try Ex 6.1 Pg13 Ch1 (M.I.A) Area of a Kite & Rhombus
