    Find area of a rhombus where diagonal are 12 cm and 9.2 cm.

    Answer:

    Let \[{{d}_{1}}\]and and \[{{d}_{2}}\]be the diagonals of the rhombus.
    \[{{d}_{1}}\] = 12 cm \[{{d}_{2}}\] and = 9.2 cm
    Area \[=\frac{1}{2}\times {{d}_{1}}\times {{d}_{2}}\]
    \[=\frac{1}{2}\times 12\times 9.2\]
    \[=\text{ }55.2\text{ }c{{m}^{2}}\]
