Question

Qual a distância do ponto A (-1,2) ao ponto B (2,6) ?

Answer 1

D = √[(x" - x')² + (y" - y')²]

D = √[(-1-2)² + (2-6)²]
D = √[(-3)² + (-4)²]
D = √[9 + 16]
D = √25
D = 5

Answer 2

Dab= raiz (x2-x1)² + (y2-y1)²
dab= raiz (2-(-1)² + (6-2)²
dab= raiz (2+1)² + (4)²
dab= raiz (3)² + 16
dab= raiz 9 + 16
dab= raiz 25
dab= 5
