Question

The diagonals of a rhombus are 7.5 cm and 12 cm. Find its area.

Solution

Given: 
Lengths of the diagonals of a rhombus are 7 . 5 cm and 12 cm.
Now, we know: Area =\[ \frac{1}{2}( d_1 \times d_2 )\]
∴ Area of rhombus \[= \frac{1}{2}(7 . 5 \times 12) = 45 {cm}^2\]

  Is there an error in this question or solution?
