You can put this solution on YOUR website!
Start with P+=+2%28L%2BW%29, P+=+70 L = length and W = width.
1) Length-to-width ratio.3 to 4.
70+=+2%283x%2B4x%29
70+=+2%287x%29 Divide both sides by 2.
35+=+7x Divide both sides by 7.
5+=+x then...
L+=+3x
highlight%28L+=+15%29feet.
W+=+4x
highlight%28W+=+20%29feet.
Try this on the other two problems.
