Answer:
j=49
Step-by-step explanation:
P = 2(L + W)
P = 200
L = W + 80
200 = 2(W + 80 + W)
200 = 2(2W + 80)
200 = 4W + 160
200 - 160 = 4W
40 = 4W
40/4 = W
10 = W.........the width is 10 yds
I'm guessing the answer is B? I tried to isolate r and I got that result. Sorry if it's wrong!
Answer:
l = P/2 -w
Step-by-step explanation:
P=2(l+w)
Divide each side by 2
P/2 = 2(l+w)/2
P/2 = l+w
Subtract w from each side
P/2 -w = l+w-w
P/2 -w =l
