Question

anybody can tell this answer ​

Answer 1

Area of the rhombus=150cm²

One diagonal=10cm(d1)

Area of a rhombus=d1d2/2

=>10×d2/2=150

=>10d2=150×2

=>10d2=300

=>d2=300/10

=>d2=30cm

Hence,correct option is .d.

Answer 2

Answer:

Option d) is correct.

$\underline{ \: \bold d _{2} \: } \: is \: 30cm$

Given data:

Area of Rhombus = 150 cm²

Length of one diagonal = 10 cm

To find:

To find the length of the other diagonal.

Step-by-step explanation:

$Area \: of \: Rhombus = \frac{d_{1} \times d_{2} }{2}$

$d _{1} = 10cm$

$d _{2} = x$

Now, substituting

$\implies 150 = \frac{10 \times x}{2}$

$\implies 300 = 10x$

$\implies x = 30$

$\boxed{d _{2} = 30}$

$\therefore \: d _{2} \: is \: 30cm$

Length of other diagonal is 30cm .
