The length of the altitude is 
Explanation:
Let ABC be an equilateral triangle.
It has sides of length 16 cm
Let AD be the altitude of the triangle.
We need to determine the length of an altitude.
Let AC = 16 cm and CD = 8 cm
Let us consider the right angled triangle ADC
Using the Pythagorean theorem, we have,

Substituting the values, we get,




The length of the altitude is 
Answer:
4/5
Step-by-step explanation:
Because mushrooms absorb water (giving it less flavor).
Answer:
The length of each side is 12cm.
Explanation:
The perimeter of a square is calculated by the formula:
P=4a, where P=perimeter, and a=length of any side, all sides being equal in a square.
From the given data we write:
48=4a
Divide both sides by 4.
12=a
The length of each side is 12cm.
