1/8 area ----- 15 square cm
8/8 area ----- 15 square cm x 8 = 120 square cm
Area of square : Area of triangle
2 : 3
(Square) 2 units ----- 120 square cm
1 unit ----- 120 square cm divided by 2 = 60 square cm
(Triangle) 3 units ----- 3 x 60 square cm = 180 square cm
Unshaded area ----- (Total area of square + total area of triangle - shaded area of the triangle - shaded area square)
(120 + 180 – 15 –15) square cm
