Lin's father will pay $17.

Step-by-step explanation:

15 ÷ 100 = 0.15.

0.15 x $20 = $3.

$20 - $3 = $17.

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
