Answer:
Perimeter of rectangle ABCD = 47.62
Step-by-step explanation:
The perimeter of a rectangle is P = 2(length + width)
You need to find length and width
If you graph, you can pick your length length and your width
Pick two points after you graph, for
Use the distance formula to find the length =
point B (4,5) will be point 1 and point C (8,-3) will be point 2
Substitute
length =
length =
length = 8.94
Use the distance formula to find the width =
point C (8,-3) will be point 1 and point D (-2,8) will be point 2
Substitute
width =
width =
width =
width =
width = 14.87
Now use formula P = 2(length + width)
P = 2(8.94 + 14.87)
Perimeter of rectangle ABCD = 47.62
