Question 1029594
.
Area of rectangle is 217800 square meter,its length twice of width,find the length?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
L*W = 217800,

L = 2W,

Hence,

(2W)*W = 217800,

{{{2*W^2}}} = 217800,

{{{W^2} = {{{217800/2}}} = {{{108900}}},

W = {{{sqrt(108900)}}} = 330 m.

Then L = 2W = 660 m.
