Question 1029588
.
AREA OF A RECTANGLE IS 10580 square meter,its length is 5 times of width, find its perimeter? 
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
Let W be the width, in meters.
Then the length L = 5W, according to the condition.

From the condition, you have this equation for the area

L*W = 10580,   or

{{{5W*W}}} = {{{10580}}},   or

{{{W^2}}} = {{{10580/5}}},   or

{{{w^2}}} = {{{2116}}},  or

W = {{{sqrt(2116)}}} = 46 m.

Hence, L = 5*46 = 230 m.

Now the perimeter is P = 2*230 + 2*46 = 552 m.

<U>Answer</U>. The perimeter is 552 m.
