x+50=y --->eqn 1
where y is the length and x is the width
2x+2y=500--> eqn2
sub y=x+50 into eqn2,
2x+2(x+50)=500
2x+2x+100=500
4x=500-100=400
x=100
sub x=100 into y=x+50,
we get y=100+50=150
thus x=100 (width) and y=150(length)

The length would be 150 and the width 100. Simple equation of 2x + 2(x+50)=500. Solve for x which is your width and the x+50 is your length.

Let y = width
Then length = y + 50
Perimeter of a rectangle = 2*width + 2*length.
500 = 2y + 2(y+50)
500 = 4y + 100
subtract 100 from both sides
4y = 400
divide through by 4
y = 100 ft (width)
y + 50 = 150 ft (length)

2(length) + 2 (width) = perimeter
length = width + 50
2(w+50) + 2(w) = 500
2w + 100 + 2w = 500
(2w + 2w) = 500 - 100
4w = 400
4w/4 = 400/4
w = 100
l = 100 + 50
l = 150
width is 100feet and length is 150feet

x the length
y the width
x + 50 = y
2x +2y = 500 => x+y=250
=> 2x + 50 = 250 x=100 => y=150

l = length
w = width
From the question
l = w +50
l + l + w + w = 500 or 2l =2w = 500
but l=w+50, so substitute for l
2(w+50) +2w = 500 expands to 2w +100 +2w = 500
combine the ws and subtract 100 from each side:
4w=400
so
w=100 l=150

L = 50 + w
Perimeter = 2(L + w) = 500
2(50+w + w) = 500
2(50 + 2w) = 500
100 + 4w = 500
4w = 400
w = 100 ft
L = 150 ft

l=length, w=width
l=w+50
perimeter=2l+2w=500
substitute: 2(w+50)+2w=500
4w+100=500
4w=400
w=100
l=150
