Let x represent the length
width (w): [tex] \frac{1}{3} [/tex]x
length (L): x
Perimeter (P) = 2L + 2w
320 = 2(x) + 2([tex] \frac{2}{3} [/tex]x)
320 = [tex] \frac{6}{3} [/tex]x + ([tex] \frac{2}{3} [/tex]x)
320 = [tex] \frac{8}{3} [/tex]x
([tex] \frac{3}{8} [/tex])320 = x
[tex] \frac{960}{8} [/tex] = x
120 = x
width = [tex] \frac{1}{3} [/tex]x
= ([tex] \frac{1}{3} [/tex])120
= 40
Answer: 40m x 120m
