What is the length of each side of the rectangle?

AB =7  and CD = 7

BC =4 and AD =4

Step-by-step explanation:

A( 1,3)

B  (1,10)

C (5,10)

D (5,3)

As we can see in the graph, the AB = CD  and BC = AD

AB = the distance between the y points since the x values are the same

AB = 10-3 = 7

AB =7  and CD = 7

BC = the distance between the x points since the y values are the same

BC = 5-1 =4

BC =4 and AD =4

BC = AD = 4; AB = CD = 7  

Step-by-step explanation:

I have plotted your rectangle in the diagram below.

BC = x₂ - x₁

      = 5  -  1

      = 4

AD = BC

     = 4

AB =  y₂ - y₁

     = 10 -  3

     = 7

CD = AB

     = 7

BC = AD = 4; AB = CD = 7
