Sample Year 9 Numeracy — Perimeter_of_composite_shape_rectangle_and_semicircle Questions

Question 1Mediumperimeter_of_composite_shape_rectangle_and_semicircle

A pendant is shaped like a rectangle 8 cm long by 6 cm wide, with a semicircle attached to one of the short sides (shown above). The semicircle has its diameter along that short side, so its radius is 3 cm. What is the perimeter of the pendant, to the nearest centimetre? (Use π ≈ 3.14.)
