Find the missing values. Diagonal- 1 ( d 1 ) Diagonal- 2 ( d 2 ) Area of rhombus 12 cm 16 cm 27 mm 2025 mm 2 24 m 57 . 6 m

For first rhombus, d 1 = 12 cm d 2 = 16 cm We know that, The area of a rhombus is equal to half of product of its diagonals. Area = A 1 = 1 2 × d 1 × d 2 = 1 2 × 12 × 16 = 6 × 16 = 96 cm 2 For second rhombus, d 1 = 27 mm Area = A 2 = 2025 mm 2 A 2 = 1 2 × d 1 × d 2 = 1 2 × 27 × d 2 2025 = 1 2 × 27 × d 2 1 2 × 27 × d 2 = 2025 27 × d 2 = 2025 × 2 d 2 = 2025 × 2 27 = 75 × 2 = 150 mm For third rhombus, d 1 = 24 m d 2 = 57 . 6 m Area = A 3 = 1 2 × d 1 × d 2 = 1 2 × 24 × 57 . 6 = 12 × 57 . 6 = 691 . 2 m 2 Thus, the complete table is as follows. Diagonal- 1 ( d 1 ) Diagonal- 2 ( d 2 ) Area of rhombus 12 cm 16 cm 96 cm 2 27 mm 150 mm 2025 mm 2 24 m 57 . 6 m 691 . 2 m 2
