A negative x a negative equals a positive so the square root of a negative value cannot be a negative value.
Set up a system of equations.
6s+b=139.5
b=3s
Substitite for b
6s+3s=139.5
9s=139.5
s=15.5

Answer:
Step-by-step explanation:
Well first you have to find the dimensions of the frame, you can find that by subtracting the dimensions of the photo from the whole dimensions so it will be the
length of the photo and frame - length of the photo = 25- 20 = 5 length of the frame
Now the width of the photo and frame - width of the photo = 20 -16 = 4 the width of the frame
ok so the Area of the rectangle = width x length = 4 x 5 = 20 the Area of the frame
Hope that helps
