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
