Answer:

1 cm

Step-by-step explanation:

<u>Sides of the picture added margin:</u>

l = 8 + 2x
w = 5 + 2x

A(margin) = 30 cm²

<u>Solution</u>:

A(margin) = Total area - A(picture)
(8 + 2x)(5 + 2x) - 5*8 = 30
4x² + 10x + 16x + 40 - 40 - 30 = 0
4x² + 26x - 30 = 0
2x² + 13x - 15 = 0
x = (-13 + √(13² + 2*4*15))/4
x = (-13 + 17)/4
x = 1 cm

Note. The other root is ignored as negative.
