- Shaded area = area of large square –
area of 2 white squares = 7^2 = 2 32 = 49 – 18
= 31 square units. - Shaded area = area of rectangle –
area of two white strips adjusted for
overlap of white strips =
20 v 6 – (20 v 1 + 6 v 1 – 1 v 1) =
120 – 25 = 95. - Shaded area =^1 ⁄ 2 the area of large circle +
(^1) ⁄ 2 the area of small circle = 72S + 12.5S =
