the length of a rectangler-shaped back yard is 8 feet less than the twice width. If 260 feet of fence is needed to enclose the find the dimensions of the yard.

Question

I don't understand anything of this question!

Answer 1

w=width

2w-8=length

P=2l+2w

260=2(2w-8)+2w

260=4w-16+2w

260=6w-16

260+16=6w

276=6w

w=276/6

w=46 feet for the width

2w-8=2(46)-8=92-8=84 feet for the length
