Question

What is the length of PQ (repeated PQ) in this diagram?

 

A. 12 units

B. 9 units

C. 54−−√ units

D. 74−−√ units

 

Answer 1

You need to find the Distance between two points:

P (-2,4)

Q (3,-3)

x₁ = -2

x₂ = 3

y₁ = 4

y₂ = -3

Distance formula: √(x₂ - x₁)² + (y₂ - y₁)²

√(3 - (-2))² + ((-3) - 4)²

√(3 + 2)² + (-7)²

√25 + 49 = √74 Option D.
