Question

the area of rohmus is 120 cm² one of its diagonal is 8 cm. find the other diagonal​

Answer 1

$\huge\red{ANSWER}$

Area of a rhombus=21×product of its diagonals

Area of a rhombus=21×d1×d2

⇒120=21×20×d2

⇒d2=20120×2=12cm

∴ the other diagonal is 12cm

Answer 2

Answer:

$\huge\underline\mathfrak\blue{answer}$

let length of the one diagonal d1=8cm

and length of the other diagonal=d2

area of the rhombus=½d1.d2=120

½8.d2=120

d2= 30 cm
