Question 857835: In a right triangle, a and b are the lengths of the legs and c is the length of the hypotenuse. If b = 7 kilometers and c = 8 kilometers, what is the perimeter? If necessary, round to the nearest tenth. Answer by JulietG(1812) (Show Source):
You can put this solution on YOUR website! a^2 + b^2 = c^2 in a right triangle
a^2 + 7^2 = 8^2
a^2 + 49 = 64
Subtract 49 from each side
a^2 = 15
Take the square root of each side
a = 3.87 (rounded to nearest tenth)
.
Let's build a fence around the triangle.
You'll need one piece the length of a, on the length of b, and one the length of c.
3.87 + 7 + 9 = 19.87
