x=-1

Step-by-step explanation:

-5x/4+3=-1/4+1/2x+5

-1/4+1/2x+5

-5x/4+3=x/2+19/4

-7x/4=7/4

-7x=7by-7

x=-1

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

the width is 57.5cm

the area is 661.25cm^2
