Explain how you find the perimeter of this right triangle even though you know the lengths of only two of the

aliya0001 [1]

Answer:

Total Perimeter of Triangle: 6.33 + 6 + 2= 14.33

Step-by-step explanation:

First of all, to find the perimeter of a triangle you need to know the measurements of all three sides. When you need to find the measurement of the slanted side, ( or hypotenuse), you need to use the Pythagorean Theorem.

$a^2 + b^2 = c^2$

Then, we insert the numbers:

$2^{2} + 6^{2} =c^2$

$2^2$ = 4

$6^2$ = 36

So, $c^2$ = 40 or $40^2$

But wait, the number is is still squared, so the square root of 40, is 6.32455532. ( The number rounded is 6.33, or in tenths, 6.3 )

Finally, we add the measurements of all the sides on the triangle to find the perimeter, which is:

14.33 or 14.3
