Problema Solution

An architect designs a rectangular flower garden such that the width is exactly two-thirds of the length. If 

280 

feet of antique picket fencing are to be used to enclose the garden, find the dimensions of the garden.

The length of the garden is 

m feet.

Answer provided by our tutors

Let


l = the length of the rectangular garden, l>0


w = the width of the rectangular garden, w>0


P = 280 ft the perimeter of the rectangular garden


The width is exactly two-thirds of the length:


w = (2/3)l


The perimeter of the garden is:


P = 2(l + w)


2(l + w) = 280


We have the following system of equations:


w = (2/3)l


2(l + w) = 280

l = 84 ft


w = 56 ft


The length of the garden is 84 feet.


The width of the garden is 56 feet.
