Question

Find the distance between the points (2,3) and (5,7) in x-y plane.

• A. 2 units
• B. 3 units
• C. 4 units
• D. 5 units

Answer 1

The correct option is D 5 units


The distance can be seen as the hypotense of the triangle.
a = 5 - 2 = 3 units
b = 7 - 3 = 4 units
C $=\sqrt{a^2+b^2}$
$=\sqrt{(3{)}^2+(4{)}^2}$
C = 5 units
