i believe it is a though i'm not good with the ending (10^4 x 10^0, i believe), i think it is 4, but it could be 3. , ?

entering that problem on the tube might get you an answer

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
