Answer:
30 units
Explanation:
The perimeter of the triangle is the sum of the two legs, or the shorter sides a and b, and the hypotenuse, the last and longest side, c.
We can already see that side a and b have the lengths of 5 and 12 units.
To find the length of c, use the formula a² + b² = c².
Substitute our a and b values into the formula and solve for c.
a² + b² = c²
5² + 12² = c²
25 + 144 = c²
169 = c²
√169 = √c²
13 = c
The third side is 13 units long.
Now we can add our values for a, b, and c together to find the perimeter.
5 + 12 + 13 = P
30 = P
The perimeter is 30 units.
Good luck ^^
