Here are the solutions to problems 9 and 10: Problem 9: This is called a _________ Step 1: Observe the properties of the shape. The shape is a quadrilateral (a four-sided polygon). It has one pair of parallel sides (the top side and the entire bottom side). The left side is perpendicular to the parallel sides. Step 2: Identify the name based on its properties. A quadrilateral with at least one pair of parallel sides is called a trapezium (or trapezoid). Since one of its non-parallel sides is perpendicular to the parallel sides, it is specifically a right-angled trapezium. The shape is a Trapezium. Trapezium Problem 10: The perimeter of the shape above is _________ Step 1: Identify all the outer side lengths of the shape. The perimeter is the total length of the boundary of the shape. • Top side: 7 cm • Left vertical side: 5 cm • Bottom side (composed of two segments): 7 cm + 3 cm = 10 cm • Slanted right side: 2 cm (as labeled in the diagram) Step
