Answer:
Length of the rectangle  =25
width of the rectangle  = 20
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Let 'x' be the width of the rectangle
Given that the length of a rectangle is 5 m more than its width
Given that Area of the rectangle = 500m² 
length of a rectangle = x +5
width of a rectangle = x
<u><em>Step(ii):-</em></u>
Area of the rectangle = length × width
              500 = x ( x+5)
           x² + 5 x = 500
       ⇒  x² + 5 x - 500 =0
       ⇒  x² +25x - 20 x - 500 =0
     ⇒  x( x+25) -20(x+25) =0
   ⇒  (x-20)(x+25) =0
  ⇒  x =20 and x=-25
we can choose x =20
<u><em>Step(iii):-</em></u>
Length of the rectangle = x +5 = 20 +5 =25
width of the rectangle  = 20
<u><em>Final answer</em></u>:-
Length of the rectangle  =25
width of the rectangle  = 20
