Find the area of shaded region, if PQRS is a square and TUVW is a rectangle. (The given figure is not drawn to scale.)
A1568 cm2
B1508 cm2
C1540 cm2
D1520 cm2
Area of square PQRS = (42 à 42) cm2 = 1764 cm2TW = UV = 42 - 26 = 16 cmPT = TU = UQ = (42 ÷ 3) cm = 14 cmArea of rectangle TUVW = (14 à 16) cm2 = 224 cm2ⴠShaded area = (1764 - 224) cm2= 1540 cm2
