Problem |
Find the length of the line segment between points (2 , 4) and (5 , 8). |
|
2 |
Step |
Let us the given points (x1 , y1) & (x2 , y2) |
(2 , 4) & (5 , 8) |
3 |
Formula: |
Distance |
\$√(x2-x1)^2 + (y2 - y1)^2\$ |
4 |
Step |
Substitute the values |
\$√(5 - 2)^2 + (8 - 4)^2\$ |
5 |
Step |
After subtraction |
\$= √(3)^2 + (4)^2\$ \$= √9+ 16\$ \$= √25\$ |
6 |
Step |
After Simplication |
\$√25\$ = \$5\$ |
7 |
Step |
So, the length of the line segment between points (2, 4) and (5, 8) is |
\$5\$ units |
