If someone could help with these questiones

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

the answers might not be correct use at own risk

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
