Question

The vertices of a triangle are located at P(0, 0), 0(4,3), and R(4,0).

Graph the triangle; use the graph paper provided. What is the perimeter
of this triangle?*

Answer 1

9514 1404 393

Answer:

12

Explanation:

The length of the hypotenuse, PQ, can be found from the Pythagorean theorem:

PQ² = QR² +PR²

PQ² = 3² + 4² = 25

PQ = √25 = 5

The perimeter is the sum of side lengths:

P = 3 + 4 + 5 = 12

The perimeter of this triangle is 12 units.
