The given question is incorrect, the correct question is this:
"The triangle shown below has an area of 25 square units. Find the missing side if x = x = x ."
The missing side is of length 7.6 units.
How do we determine the area of an equilateral triangle?
The area of an equilateral triangle is determined using the formula
Area = (√3/4)a²,
where a is the length of the side of the given triangle.
How do we solve the given question?
In the given question, we are said that each side of the triangle is x in length, that is, it is an equilateral triangle with an area of 25 sq. units.
Substituting values in the formula: Area = (√3/4)a², we get
25 = (√3/4)x²
or, x² = (25*4)/√3
or, x = √((25*4)/√3) = √(100/√3) = 7.6 units
∴ The missing side is of length 7.6 units.
