The area of a rectangular land is $432$ m². Ratios of length and breadth of this land to another are $3:4$ and $2:5$ respectively. The area of the other land is—

a $720$ m²
b $1080$ m²
c $1440$ m²
d m²

Area scales as the product of the length and breadth ratios. The other land $= 432 \times \dfrac{4}{3} \times \dfrac{5}{2} = 432 \times \dfrac{10}{3} = 1440$ m².
