Question 901125
P = 2L + 2W (remember, it's a fence around)
P = 62
L = 2W + 10
Substitute the value of L from the bottom equation into the top
P = 2L + 2W
62 = 2(2W+10) + 2W
Distribute
62 = 4W+20+2W
62 = 6W+20
Subtract 20 from each side
42=6W
Divide each side by 6
7 = W
If the width is 7, then the length is twice that plus ten, or 14+10=24
24+24+7+7=62
