Question

calcule a distância entre os pontos a e b ponto a 1,1 ponto b 4,3​

Answer 1

d=(xb-xa)²+(yb-ya)²

d=√(4-1)²+(3-1)

d= √(9)+(4)

d= √13

Answer 2

$\large \boxed{ \begin{array}{l} \sf{d_{AB} = \sqrt{(x_A - x_B) {}^{2} + (y_A - y_B) {}^{2} } } \\ \\ \sf{d_{AB} = \sqrt{(1 - 4) {}^{2} + (1 - 3) {}^{2} } } \\ \\ \sf{d_{AB} = \sqrt{( - 3) {}^{2} + ( - 2) {}^{2} } } \\ \\ \sf{d_{AB} = \sqrt{9 + 4} } \\ \\ \boxed{ \boxed{\sf{d_{AB} = \sqrt{13} \approx3,60 } }}\end{array}}$
