Question

the area of a rhombus is 300 square metre if one of its diagonals is 30m
find the other diagonal



​

Answer 1

area of rhombus = 1/2 × diagonal 1 × diagonal 2

300 square m= 1/2 × 30 × diagonal

300 = 15 × diagonal

300/ 15 = diagonal

20 m = diagonal

Answer 2

$\boxed{Hey\:mate}$

$\boxed{Here\:is\:your\:answer}$

We know that,

area of rhombus=1/2×d×d'

=>300=1/2×30×d'

=>300=15×d'

=>d'=300/15

=>d'=20 cm
