TASK (GRADE D) EXTENSION (GRADE D) Calculate the area of the compound shapes below: Calculate the area of the compound shapes below: 8cm (a) 13cm 15cm (b) Creative Thinker Effective Participator Independent Enquirer Reflective Learner Self Manager Team Worker PLT Skills AREA OF COMPOUND SHAPES Which ones are you using? MINI-PLENARY James is painting a wall as shown by the shaded region below: Work out the area of the largest rectangle and subtract the area of the two smaller rectangles (door and window). Area of largest rectangle = length x width Area of largest rectangle = 5 x 2.5 Area of door = length x width Area of door = 2 x 0.8 Area of window = length x width Area of window = 1.8 x 1 Therefore, James has enough paint to cover the wall.
