the complete question is
Heron’s formula: Area Use the triangle pictured to calculate the following measurements. Perimeter: p = units Semiperimeter: s = units Area: A ≈ square units. The triangle is 8 by 12 by 10
Part a) Calculate the Perimeter:
The perimeter of the triangle is the sum of its sides.
the answer Part a) is
The perimeter is equal to
Part b) Calculate the Semi-perimeter:
The semiperimeter of a polygon is half its perimeter.
the answer part b) is
the semiperimeter is equal to
Part c) Calculate the Area
we know that
You can calculate the area of a triangle if you know the lengths of all three sides, using a formula that
It is called "Heron's Formula"
where
s: is the semi-perimeter
a, b, c are the length sides.
the answer Part c) is
To the South. Urban to Suburban
Answer:
I have question why is the graph?!
Answer:
1. both stone and paper fall due to the effect of the force of gravity.
2. stone is obviously heavier than paper.
3. stone falls faster than the paper...this is due to the air resistance....but note if it were in vacuum they both fall at same time since they are all acted upon by the same intensity of the force of gravity.. hope I've helped
