Ans.Area of triangle A = Half of area of rectangle = 1/2 x 12 = 6 square cm. Area of square B = 4 complete squares + 8 half squares + 4 quarter squares = 4 + 1/2 x8 + 1/4 x 4 = 4 + 4 + l = 9 square cm Area of shape C = 2 + 1/2 x 0 + 2 = 2 + 2 = 4 square cm Area of shape D = 5 + 1/2 x 2 + 0 = 5 + 1 = 6 square cm Area of shape E = 18 + 1/2 x 6 + 0 = 18 + 3 = 21 square cm Area of shape F = 4 + 1/2 x 0 + 4 = 4 + 4 = 8 square cm.
