Hello from MrBillDoesMath!

Answer:

24


Discussion:

In a right triangle with legs 6, and 8, by the Pythagorean theorem the hypotenuse is sqrt( 6^2 + 8^2) = sqrt (36 + 64) = sqrt(100) = 10.

The perimeter is the sum of the side (and hypotenuse) lengths:

Perimeter = 6 + 8 + 10 = 24




Thank you,

MrB

The perimeter of the right triangle is 24 feet.

Given the following data;

  • Adjacent = 6 feet
  • Opposite = 8 feet

To find the perimeter of the right triangle;

Mathematically, the perimeter of a right triangle is given by the formula;


P = A + B + C

But we were only given two (2) of its sides or legs, so we would have to solve for the third side (hypotenuse) by using the Pythagorean theorem.


C^(2) = A^(2) + B^(2)

Where;

C is the hypotenuse of a right triangle.

A is the opposite side of a right triangle.

B is the adjacent side of a right triangle.

Substituting the values


C^(2) = 8^(2) + 6^(2)\\\\C^(2) = 64 + 36\\\\C^(2) = 100

Taking the square root of both sides, we have;


C = √(100)

Hypotenuse, C = 10 feet.

Next, we find the perimeter of the right triangle;


P = 8 + 6 + 10

Perimeter, P = 24 feet.

Therefore, the perimeter of the right triangle is 24 feet.
