We need to identify the perimeter of the rectangle EFGH which has points as below: G (-3, 4) H (2, 2) E (1, -1) F (-4, 1) The distance of EF, we have it: d² = (-4-1) ² + (1--1)² = 25 + 4 = 29 d = √29 The distance from point F to point G:  d² = (-4--3)² + (1-4)² = 1 + 9 d = √10 Hence, we can solve for the perimeter as below: Perimeter EFGH = 2L + 2W Perimeter EFGH = 2(√29) + 2(√10) Perimeter EFGH = 17.09 units The answer is the second item in the choices or the letter B which is 2√10 + 2√29 units.
