Question

$\huge \mathcal{ \pink{Qu} } \red{estio} \pink{n}$

The area of a rhombus is 240 cm² and one of the diagonals is 16 cm. Find the other diagonal.
​

Answer 1

Step-by-step explanation:

Area of rhombus,Ar is given by:

$ar = \frac{pq} {2}$

where p and q are the diagonals of the rohmbus.

So,

$240 = \frac{16 \times q}{2}$

Thus other diagonal is 30 cm

Answer 2

$\sf\fbox\red{A}\sf\fbox\green{N}\sf\fbox\blue{S}\sf\fbox\pink{W}\sf\fbox\orange{E}\sf\fbox{R}$

Area of rhombus,Ar is given by:

Ar=pq/2

where p and q are the diagonals of the rohmbus

so,

240=16×q/2

q=30

Thus other diagonal is 30cm
