Let us assume that W is the width of the border tile (with the units of ft.). Also, let A be the are which is equivalent to 296 sqft.
<span>We establish this mathematical equation:
(28+2W)(42+2W)−28×42=296
</span>
Then algebraically manipulate:(14+W)(21+W)−14×21=74
<span>W2+35W−74=0</span>
Lastly, we factor:
(W+37)(W−2)<span>=0
</span>W=2
