Question : If the numerical values of the height and the area of an equilateral triangle are the same, then the length of each side of the triangle is:

Option 1: 2 units

Option 2: 4 units

Option 3: 5 units

Option 4: 8 units

Team Careers360 · Accepted Answer

Correct Answer: 2 units

Solution :
Let the side of an equilateral triangle be $a$ units.
Let its height be $h$.
Using Pythagoras theorem, we get,
$a^2 = h^2+(\frac{a}2)^2$
⇒ $h=\frac{\sqrt{3}}2a$
Area of equilateral triangle = $\frac{\sqrt{3}}{4}a^2$ sq. units
According to the question,
$\frac{\sqrt{3}}2a=\frac{\sqrt{3}}{4}a^2$
⇒ $a=2$ units
Hence, the correct answer is 2 units.
