Question

rectangle abcd is graphed on a coordinate plane. the following are the vertices of the angle : a(2,-3), b (4,-3), c(4,5), and d (2,5). what is the perimeter of rectangle abcd?

Answer 1

P=20

Explanation:

first find the distance between the points:

AB, BC,CD and DA

A(2,-3) , B(4,-3) , C(4,5) , D (2,5)

distance d= √(x2-x1)^2+(y2-y1)^2

for AB= d= √(4-2)^2+(-3-(-3))^2

AB=2

same thing for the rest of the lines

BC=√(4-4)^2+(5-(-3))^2

BC=8

CD=2

DA=8

perimeter=8+8+2+2=20
