Question

What is the length of a side of rhombus JKLM

Answer 1

Solve for X. 3X=2X+4
X=4
So each side = 12

Answer 2

we know that

In a Rhombus all sides are congruent

so

`MJ=JK=KL=ML`

we have

`MJ=3x\ units\\JK=(2x+4)\ units`

equate MJ and JK

`3x=2x+4`

Solve for x

`3x-2x=4`

`x=4\ units`

Find the length side of the rhombus

`MJ=3x`

`MJ=3*4=12\ units`

therefore

the answer is

The length side of the rhombus is
`12\ units`
