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

Case (i) Diagonal ( d 1 ) = 12 cm and Diagonal ( d 2 ) = 16 cm We know that, area of rhombus = 1 2 × d 1 × d 2 = 1 2 × 12 × 16 = 6 × 16 = 96 cm 2 Therefore, area of rhombus = 96 cm 2 Case (ii) Diagonal ( d 1 ) = 27 mm and area of rhombus = 2025 mm 2 We know that, area of rhombus = 1 2 × d 1 × d 2 ⇒ 2025 = 1 2 × 27 × d 2 ⇒ 4050 = 27 × d 2 ⇒ d 2 = 4050 27 ⇒ d 2 = 150 mm Case (iii) Diagonal ( d 1 ) = 24 m and Diagonal ( d 2 ) = 57 . 6 m We know that, area of rhombus = 1 2 × d 1 × d 2 = 1 2 × 24 × 57 . 6 = 12 × 57 . 6 = 691 . 2 m 2 Therefore, area of rhombus = 691 . 2 m 2 Diagonal ( d 1 ) Diagonal ( 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
