the width of a rectangle is 9m less than it's legnth if the perimeter of the rectangle is 54m find the legnth of the garden

Perimeter of rectangle = 2(l+w)

So, 54cm = 2(l+9cm)

=> 54cm = 2l + 18cm

=> 54cm - 18cm = 2l

=> 36cm = 2l

=> 36cm/2 = l

=> 18cm = l

if this is really you s much. i only have 3 points left and i have 2 questions to ask
