Distance between points (-12, 4) and (-20, 16)

Given Coordinates: x₁ = -12  y₁ = 4,  x₂ = -20  y₂ = 16
Distance Formula: d = √(x₂ − x₁)² + (y₂ − y₁)²
Substitute the given coordinates into the Distance Formula and Simplify:
d = √(-20 − (-12))² + (16 − 4)²
d = √(-20 + 12)² + (16 − 4)²
d = √(-8)² + 12²
d = √64 + 144
d = √208
d = √16 * 13
d = √16 * √13
d = 4√13
Therefore, the distance between the points (-12, 4) and (-20, 16) is equal to 4√13
Note: As a decimal number, 4√13 ≈ 14.422205101856
