Question

Rhombus J K L M is shown. The length of J K is 2 x + 4 and the length of J M is 3 x.

What is the length of a side of rhombus JKLM?

4 units
8 units
12 units
16 units

Answer 1

12 units

Explanation:

Properties of Rhombus:

1. length of all sides are equal.

2. Diagonals bisect each other at right angles

As the length of all sides are equal,

JM = JK

3x = 2x + 4

Subtract 2x from both sides,

3x - 2x = 4

x = 4

JM = 3*4 = 12 units
