Each side of a rhombus is 20 cm long and one of its diagonals is 24 cm in length, find the area of this rhombus?

vodomira [7]

Answer:

AB = 20 CM

OA = 1

__ × 24 cm

= 12 cm

AOB = 90 °

OB² == AB² - OA ²

$( {20}^{2} ) - ( {12}^{2} ) \\ = 400 - 144 \\ = 256 \\$

$ob \: = \sqrt{256} = 16 \\ bd \: = 2 \times ob \\ = 2 \times 16 \\ = 32cm \: \\$

AREA OF ABCD IS

$\frac{1}{2 } \times ac \times bd \\ = \frac{1}{2} \times 24 \times 32 \\ 384cm$
