It is almost a must to draw a diagram but I can't do that on the computer. It will help you to do so.

height of inside poster = w+25

width of inside poster = w

area of inside poster =w*(w+25)

Border is 5 cm on each side; therefore, its height is w+25+top5cm+bottom 5cm=w+35

Border width = w + left 5 cm + right 5 cm = w + 10 cm.

area of entire unit is (w+35)*(w+10)

area of inside poster is w*(w+25)

The border is 1350 cm

area entire unit-1350=area inside unit.

(w+35)*(w+10)-1350 = w(w+25)

Solve for w, which is the width of the inside poster. Add 25 to that to obtain the height. Then add 10 to each to obtain the dimensions of the entire frame. Post your work if you get stuck.
