Level 3 PSLE
The figure is made up of three rectangles. A straight line drawn across the rectangles, divides the figure into two parts: shaded and unshaded.
The perimeter of the shaed part is 8 cm longer than the perimeter of the unshaded part. What is the length of AB?
What is the area of the shaded part?
