AREA OF A RECTANGLE IS 10580 square meter,its length is 5 times of width, find its perimeter?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
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
 =  , or
 =  , or
 =  , or
W =  = 46 m.
Hence, L = 5*46 = 230 m.
Now the perimeter is P = 2*230 + 2*46 = 552 m.
Answer. The perimeter is 552 m.
