Answer:
Step-by-step explanation:
Let the length of each side be x. We can divide the triangle into two to get two right angled triangles which side will be x (hypotenuse), 4.5 (height), x/2 for base.
Using Pythagoras's theorem
x² = 4.5² + (x/2)²
x² = 81/4 + x²/4
x² - x²/4 = 81/4
3/4x² = 81/4
x² = 27
x = √27 = 3√3 in
