Question

Calculati aria patratului MNPQ, stiind ca M(3, 1) si P(-3, 7).

Answer 1

$d(M,P) =\sqrt{ (x_{P}- x_{M}) ^{2} + (y_{P}- y_{M}) ^{2}} \\ d(M,P) =\sqrt{ (-3-3 ) ^{2} + (7-1) ^{2}} \\ d(M,P) =\sqrt{ (-6 ) ^{2} + (6) ^{2}} \\ d(M,P) =\sqrt{ 36+ 36} \\ d(M,P) =\sqrt{ 72} \ \\ \\ A_{MNPQ}= l^{2} \\ \\ A_{MNPQ}= 72$
