Answer:
Distance = 20 units
Explanation:
Points to remember
Distance formula
Length of a line segment with end points (x1, y1) and (x2, y2) is given by,
Distance = √[(x2 - x1)² + (y2 - y1)²]
To find the distance between give 2 points
Here (x1, y1) = (-8, -8) and (x2, y2) = (4, 8)
Distance = √[(x2 - x1)² + (y2 - y1)²]
= √[(4 - -8)² + (8 - -8)²]
= √[(4 + 8)² + (8 + 8)²]
= √[12² + 16²] = √[144 + 256)
= √400 = 20
Therefore distance = 20 units
