The correct Answer is:
To solve the problem, we need to find the length of each side of an equilateral triangle given that the numerical value of its perimeter is equal to \(\sqrt{3}\) times its area. ### Step-by-Step Solution: 1. **Define the Side Length**: Let the length of each side of the equilateral triangle be \(a\). 2. **Calculate the Perimeter**: The perimeter \(P\) of an equilateral triangle is given by: \[ P = 3a \] 3. **Calculate the Area**: The area \(A\) of an equilateral triangle can be calculated using the formula: \[ A = \frac{\sqrt{3}}{4} a^2 \] 4. **Set Up the Equation**: According to the problem, the perimeter is equal to \(\sqrt{3}\) times the area: \[ 3a = \sqrt{3} \cdot A \] Substituting the expression for the area \(A\): \[ 3a = \sqrt{3} \cdot \left(\frac{\sqrt{3}}{4} a^2\right) \] 5. **Simplify the Equation**: This simplifies to: \[ 3a = \frac{3}{4} a^2 \] 6. **Rearranging the Equation**: Multiply both sides by 4 to eliminate the fraction: \[ 12a = 3a^2 \] Rearranging gives: \[ 3a^2 - 12a = 0 \] 7. **Factor the Equation**: Factor out \(3a\): \[ 3a(a - 4) = 0 \] 8. **Solve for \(a\)**: Setting each factor to zero gives: \[ 3a = 0 \quad \text{or} \quad a - 4 = 0 \] Thus, \(a = 0\) (not valid for a triangle) or: \[ a = 4 \] ### Conclusion: The length of each side of the triangle is \(4\) units.
