The formula of the perimeter of a rectangle is equal to:
Perimeter = 2L + 2W
Forming the equation.
<span>Perimeter = 2L + 2W
</span>17.6 = 2L + 2W
Getting the lengths.
<span>17.6 = 2L + 2W
</span>2L = 17.6 - 2W
L = (17.6 - 2W) / 2
<span>17.6 = 2L + 2W
</span>2W = 17.6 - 2L
<span>W = (17.6 - 2L) / 2</span>
Hi!
you are trying to find the perimeter of the lawn and by the looks of it, it's a rectangual so you would add up all the side.
42+42= 84
27+27= 54
84+54= 138
Daniel will need 138 metal border. :)
