Step-by-step explanation:

Step 1: Define

Identify.

Point A(2, 10)

Point C(14, 1)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm
