Find the perimeter and area of the polygon with the given vertices. Round your answers to the nearest tenth, if necessary.

E(6,−2), F(6, 5), G(−1, 5)

Respuesta :

24.5, 2 sides are 7 and 7x7=49. then you have to divide by two because it is a triangle so the answer is 24.5

Answer:

p: 23.9

a: 24.5

Step-by-step explanation:

distance formula: [tex]\sqrt{(x_{2} -x_{1} )^{2} +(y_{2} -y_{1} )^{2} }[/tex]

GF: width: (-1,5) (6,5): 6 - (-1) = 7 or [tex]\sqrt{(6-6)^{2} +(5-(-2)^{2} }[/tex]= 7

FE: length: (6,5) (6,-2): 5 - (-2) = 7 or [tex]\sqrt{(-1-6)^{2} +(5-5)^{2} }[/tex]= 7

GE: (-1,5) (6,-2): [tex]\sqrt{(-1-6)^{2} +(5-(-2)^{2} } = 7\sqrt{2} = 9.89949493[/tex]

area: (7×7) ÷2 = 49: 49 ÷ 2 = 24.5

perimeter: 7 + 7 + 9.9 = 23.9
