Question

if the diagonal of rhombus are 9 centimetre and 12 cm find its side

Answer 1

Answer:

Step-by-step explanation

d1=9

d2=12

Diadonals are perpendicular bisectors thus

By pythaghorean theorom

4.5^2+x=6^2

=20.25+x=36

X=√15.75

Answer 2

Answer:7.5cm

Step-by-step explanation

We know diagonals of rhombus perpendicular bisects each other.

OD=6CM

OC=4.5CM

ANGLE DOC=90 degree

CD=?

CD^2=OD^2+OC^2

=>6^2+4.5^2

=>36+20.25

=>56.25

=>CD=√56 .25

=>CD=7.5

Hence the sides of rhombus are 7.5cm.
