Question

Find the area of rhombus the length of whose diagonals are 12 dm and 17 dm

Answer 1

area of rhombus = d1 × d2

_______

2

=(12×17)÷2

=102

Answer 2

Area of a rhombus with diagonal d1 and d2 is given as:

$area \: of \: rhombus \: = \frac{1}{2} (d_1 \times d_2)$

Given that d1 = 12dm and d2 = 17dm

$area \: = \frac{1}{2} (12 \times 17) \\ \\ area = 17 \times 6 = 102 \: {dm}^{2}$
