Question

The area of a rhombus is 240cm square and one of the diagonal is 16 cm find the other diagonal​

Answer 1

Answer:

area of rhombus=1/2 *product of diagonals

240=1/2*16*y

240=8*y

240/8=y

y=30

therefore length of other diagonal= 30cm

Answer 2

Given :

• The area of a rhombus is 240cm² and one of the diagonal is 16 cm .

To find :

• The other diagonal .

Solution :

$\sf Area \: of \: Rhoumbus = \frac{1}{2} d {}^{1} \times d {}^{2}$

Where d¹ and d² are diaganals

$∴ \sf \: \frac{1}{2} \times d {}^{1} \times d {}^{2} = 240 \\ \sf \: d {}^{1} \times 30 = 240 \times 2 \\ \sf \: d {}^{1} = \frac{240 \times 2}{30}$
