Final answer:
The perimeter of a right triangle is calculated by adding the lengths of all three sides, while the area is calculated using the formula (1/2) * base * height.
Step-by-step explanation:
The formula for the perimeter of a right triangle is given by:
perimeter = a + b + c
And the formula for the area of a right triangle is given by:
area = (1/2) * a * b
Given the length of the two sides, a and b, you can use these formulas to calculate the perimeter and area of the right triangle.
