Problema Solution
A rectangylar plot of 800 ft needs to be enclose by a fence if the
Lenght id twice the wifth how much of the fence is needed?
Answer provided by our tutors
let width = x;
so length = 2x;
given,
Area = 800;
=> x*2x = 800;
=> x^2 = 400
=> x= 20;
So, fence needed = perimeter = 2(length + breadth) = 2 (x+2x) = 6x = 120ft
