Ответ:
W = 4/5L
5120 = L(4/5L)
5120 = 4/5L^2
5120 * 5/4 = L^2
6400 = L^2take the square root of both sides, eliminating the ^2
sqrt 6400 = L
80 = Llength is 80 ft <===
W = 4/5L
W = 4/5(80)
W = 64...width is 64 ft

Step-by-step explanation:
The maximum possible distance between two posts for the fence will be given by HCF ( highest common factor ) of 24 and 64
24 = 8 x 3
64 = 8 x 8
highest common factor is 8 .
So distance between two poles ( maximum separation ) will be 8 m .
Ans : 8 m .
