Question
Area of the rhombus shown below is 48 square inches. What is the value of x?
- 3
- 8
- 16
- 6
The correct answer is: 3
In the rhombus shown above,
d1 = 8 + 8 = 16 units
d2 = x + x = 2x units
Given: Area of the rhombus is 48 square inches.
Then,
⋅ (d1d2) = 48
Substitute 16 for d1 and 2x for d2.
⋅ (16 ⋅ 2x) = 48
8 ⋅ 2x = 48
16x = 48
Divide each side by 16.
x = 3
