Please help me with..... A rectangular garden is 50 feet longer than it is wide its perimeter is 284 feet
zmey [24]
P=2 (l+w)
we know P=284
we also know that l= w+50
so replace l in the equation with w+50

284=2 (w+50+w)
284=2 (2w+50)
divide both sides by 2
142=2w+50
subtract 50 on both sides
98=2w
divide both sides by 2
49=w
so width is 49, and we need to add 50 to it to find the length
l= 49 +50
l=99

I need help finding my variable
Oksi-84 [34.3K]
The length is two times its width, and the perimeter equals 24. 

All the sides added up equal 24.

4 and 8 could be the width and the length of the rectangle.

4*2= 8 and

4+4+8+8= 24

width= 4 length= 8

I hope this helps!
