Answer: 4.126 km
Step-by-step explanation:
First, We have to find total span of both bridges
As Question indicates 'total' ,that is, we have to find bridge length in total ( You can join Bridges to have better understanding)
Now, Walkway over hundson Bridge length= 2.063 km
Amping bridge length= 2.07 km
So, Total span of both bridges = 2.063+2.07 = 4.133 km
b) Now Leah wanna walk across and back on walkway over hudson ,that is, she wanna return to starting point from where she walk forth
So,that means, she walk double distance of length of walkway over hudson
So, total distance = 2× 2.063
= 4.126 km
hope this helps,

Answer:
The height is 4.472
Step-by-step explanation:
That formula is Heron's formula.
Where "s" is calculated like this:
s = (a + b + c) / 2
In this case:
a = 14
b = 12
c = 6
replacing:
s = (14 + 12 + 6) / 2
s = 16
Now we calculate the area:
A ^ 2 = 16 * (16−14) * (16−12) * (16−6)
A ^ 2 = 1280
A = 35.777
The area of the triangle is:
A = b * h / 2
In this case we will take the base as the longest side of the triangle, that is to say = 14
Thus:
h = A * 2 / b
h = 35.777 * 2/16
h = 4.472
So the height is 4.472
