Find the perimeter of the rectangle.

Question

Answer 1

Use distance formula to find the length and width of a rectangle.

AB = √(3 - 0)² + (0 - 3)² = √(3)² + (- 3)² = √9+9 = √18 = 3√2

BC = √(3 - 1)² + (0 - (-2))² = √(2)² + (-2)² = √4+4 = √8 = 2√2

Perimeter of a rectangle = 3√2 + 3√2 + 2√2 + 2√2 = 10√2 units
