Question

What is the length of each side of the rectangle?​

Answer 1

BC = AD = 4; AB = CD = 7

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

Answer 2

AB =7 and CD = 7

BC =4 and AD =4

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
