B

Step-by-step explanation:

Geneva is 12 degrees celsius colder than her hometown, and on the graph we can see that Geneva is -3 degrees celsius, so -3 + 12 = 9, so it's San Francisco which is 9 degrees celsius.

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
