A rhombus is formed by joining midpoints of the sides of a rectangle in the suitable order. If the area of the rhombus is 2 square units, then the area of the rectangle is

In the rhombus PQRS,

Diagonal $\mathrm{PR}=$ Length of rectangle $=d_{1}$

Diagonal $\mathrm{BS}=$ Breadth of rectangle $=d_{2}$

Area of rhombus $=\frac{1}{2} d_{1} d_{2}$

$\Rightarrow \frac{1}{2} d_{1} d_{2}=2 \Rightarrow d_{1} d_{2}$

$=4$ sq. units

$=$ Area of rectangle
