You can put this solution on YOUR website!
Let the width = w.
The length is given as "10 feet more than twice the width". So l+=+10%2B2w
The perimeter is givenb as 260 feet. You know the perimeter of a rectangle is
P+=+2w+%2B+2l
260+=+2w+%2B+2%2810%2B2w%29+
260+=+2w+%2B+20+%2B+4w+
260+-+20+=+2w+%2B+4w+
240+=+6w+
40+=+w+
Check your answer.
If w = 40 , then length = 10+80 = 90.
Is 2*40 + 2+90 = 260??
