Perimeter is the sum of all the sides for any figure.
In a rectangle opposite sides are equal .If the length and width of rectangle are l and w then Perimeter = 2(l+w)
In the given question
[tex] L= 5 \frac{1}{2}W= 3 \frac{1}{2} [/tex]
Perimeter = [tex] 2( 5 \frac{1}{2}+3 \frac{1}{2} )=2(\frac{11}{2}+\frac{7}{2} )=2(\frac{18}{2} )=2(9)=18 [/tex]
Perimeter of rectangular is 18m
