Question 12
Find the shaded area in the diagram. The large square has side length 20 cm. Use π=3.14. Give the area in square centimetres.
Interpret the curves as the quarter-circles indicated by the source construction: one has radius 20 cm and the two smaller ones have radius 10 cm; the internal lines bisect the square.
