Lengths of the diagonals of a rhombus are 11.2 cm and 7.5 cm (Given in que)

So by formula .

Area of rhombus is ;- 1/2 ×d1 ×d2

= 1/2 ×84

= \frac{1}{2} \times 11.2 \times 7.5

= 42 {cm}^{2}

Area of rhombus is 42cm^2

hope it helps...

Answer 2

First diagonal (d¹) = 12.2 cm

Second Diagonal (d²) = 9.4 cm

Area of Rhombus = ½×d¹×d²

Area = ½×12.2×9.4

= 57.34 cm²
