(8,-2) , ( 4,1) എന്നീ ബിന്ദുക്കൾ തമ്മിലുള്ള അകലം

A5

B8

C6

D12

Answer:

A. 5

Read Explanation:

അകലം =(x1−x2)2+(y1−y2)2=\sqrt{( x_1-x_2)^2 + (y_1-y_2)^2}

x1=8,x2=4,y1=−2,y2=1x_1= 8 ,x_2= 4 , y_1= -2 , y_2 =1

=8−4)2+(−2−1)2=\sqrt{8- 4)^2 + (-2-1)^2}

=42+(−3)2=\sqrt{4^2+(-3)^2}

=16+9=\sqrt {16+9}

=25=\sqrt {25}

=5=5
