W
)
=
1350
This equation is the total height adding 5 for the top border and 5 for the bottom border. Then multiplying the total height by the width of the border 5, time 2 because there are two sides that are tall Then adding 5 times two widths.
Now substitute the value of W + 25 for T this gives
# 5 xx (2 xx W + 25 +10)+ 5 xx 2W = 1350 solving for W
