(iv ) You ask the students to provide shapes with a perimeter of 52 cm. You expect at least one square Instead, a cut-out symmetrical diamond shape is provided. Its major diagonal is 24 cm long. For a chance to explore Pythagoras's Theorem, you challenge the students to find the area of the shape without measuring the length of its minor diagonal, Below, show full working to calculate the area. [Hint: Symmetry implies that the diagonals cross at 90. ] Perimeter = 52 cm iz cm Major diagonal = 24 cm 12 0m 12 5m
