Question

Find the perimeter of a quadrilateral with vertices at G (1, 6), H (2.5, 4), I (1, 2), K (-0.5, 4). Round your answer to the nearest hundredth when necessary.
Select one:
a. 5 units
b. 12.5 units
c. 7.5 units
d. 10 units

Answer 2

its between c and d I just cant deside

Answer 3

Use the distance formula to find the distance of each side of the quadrilateral and then add the lengths of each side to find the perimeter.

Answer 4

like this The length of GH is
[2.5 - (1)] = 1.5

The length of HI is
√[(1-2.5)^2 + (2-4)^2] = √[2.25+4] = 2.5

The length of IK is
[1 - (-0.5)] = 1.5

The length of GK is
√[[1 - (-0.5)]^2 + (6-4)^2] = √[1.22+4] = 2.29

The perimeter is the sum:
1.5+2.5+1.5+2=7.5 units

Answer 5

or like this GH=2.5
IK=2.5
IH=2.5
GK=2.5

Perimeter =10

Answer 6

GH=2.5
IK=2.5
IH=2.5
GK=2.5

perimeter = 10
