Each leg must be greater than 1/2 the base
so the range is 7.5 < L < ∞
Answer:
17 cm
Step-by-step explanation:
1. Depth in fresh water
p(water) = hρg
d(max) = h = p/(ρg)
Convert atmospheres to pascals
0.056 atm × 101 325 Pa/1 atm = 5670 Pa
h = 5670 Pa/(1000 kg·m⁻³ × 9.806 m·s⁻²) × (1 kg·m⁻¹s⁻²/1 N) = 0.579 m
2. Depth in Dead Sea
d(max) = 5670/(1400 × 9.806) = 0.413 m
3. Difference
Difference = 0.579 – 0.413 = 0.17 m = 17 cm
The difference in d(max) is 17 cm.
This is an equilateral triangle of height a√3/2 where a is the side length. So the area is ½a.a√3/2=a²√3/4.
So a²=25 and a=5cm. Therefore the perimeter is 3a=15cm.
The perimeter will be
.. P = 2√(16^2 +30^2) = 2*34 = 68
