<PRE><B>Question 149568</B>
The length of a rectangular garden is twice its breadth. A square playground measuring 600 m2 occupies one-third of the total area of the garden. The length of the garden in metres is:
:
If {{{1/3}}} = 600, the total will be 3*600 ft
:
Let x = garden width
then
2x = garden length
:
The simple equation:
2x * x = 3(600)
;
2x^2 = 1800
:
x^2 = {{{1800/2}}}
;
x^2 = 900
x = {{{sqrt(900)}}}
x = 30 m is the width
then
60 m = the length
