Question

quadrilaterals
what is the length of a side of rhombus jklm?
8 units
16 units
12 units

Explanation:

Step1: Recall property of rhombus

In a rhombus, all sides are equal. So, $3x=2x + 4$.

Step2: Solve the equation for x

Subtract $2x$ from both sides: $3x-2x=2x + 4-2x$, which gives $x = 4$.

Step3: Find the side - length

Substitute $x = 4$ into the expression for a side. Using $3x$, we have $3\times4=12$ units.

Answer:

12 units
