48
Step-by-step explanation:
The length of the third side is about 7.81 inches and the perimeter of the triangle is about 18.81 inches
Answer:
A:-3 B:6 C:17
Step-by-step explanation:
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.
