Answer:
length = 30 cm
Breadth = 10 cm
Step-by-step explanation:
Length = x cm
Breadth = (1/3)x
Perimeter = 80 cm
2(length + breadth) = 80
2* (x + (1/3)x) = 80
![2*(\frac{3}{3}x+\frac{1}{3}x) = 80\\\\2*(\frac{4}{3}x) = 80\\\\\frac{8}{3}x = 80\\\\x = 80*\frac{3}{8}\\\\x = 10*3](https://tex.z-dn.net/?f=2%2A%28%5Cfrac%7B3%7D%7B3%7Dx%2B%5Cfrac%7B1%7D%7B3%7Dx%29%20%3D%2080%5C%5C%5C%5C2%2A%28%5Cfrac%7B4%7D%7B3%7Dx%29%20%3D%2080%5C%5C%5C%5C%5Cfrac%7B8%7D%7B3%7Dx%20%3D%2080%5C%5C%5C%5Cx%20%3D%2080%2A%5Cfrac%7B3%7D%7B8%7D%5C%5C%5C%5Cx%20%3D%2010%2A3)
x = 30cm
length = 30 cm
breadth =
cm
