Answer:
2√(13)= 7.21
Explanation:
The formula for Pythagoras' theorem is a² + b² = c². In this equation, c is the longest side of a right-angled triangle. This line is also known as the hypotenuse. A and b represent the other two sides of the triangle.
so h = √(6²+4²) = 2√(13)= 7.21 (approximately)
