Question

Find the area of rhombus whose diagonals are of length 10cm and 8.2cm.

Answer 1

area of rhombus=1/2(d1×d2)
=1/2(10×8.2)
=1/2(82)
=41cm^2

Answer 2

$area = \frac{1}{2} d1 \times d2 \\ \: \: \: \: \: \: \: \: \: \: = \frac{1}{2} \times 10 \times 8.2 \\ \: \: \: \: \: \: \: \: \: \: = 41 {cm}^{2}$
