Question

Find the perimeter of a triangle with these vertices (5,1),(-2,1),(-2,-4)

Answer 1

12+√74 ≈ 20.60

Explanation:

The side lengths of this right triangle are 5 and 7 units, so the length of the hypotenuse is ...

b² = a² +c² = 5² +7² = 74

b = √74

The perimeter is ...

P = a + b + c = 5 + √74 + 7

P = 12+√74 ≈ 20.60
