Where to start on how to solve the formula: the perimeter of a rectangle
garden is 74 yards the width of the garden is two yards less than twice the length.
find the width and length?
:
Start with the perimeter formula
2L + 2W = 74
simplify, divide by 2
L + W = 37
:
"the width of the garden is two yards less than twice the length."
W = (L - 2)
:
Using our simplified perimeter formula, replace W with (L-2)
L + (L-2) = 37
2L = 37 + 2
2L = 39
L = 39%2F2
L = 19.5
:
Find W:
W = L - 2
W = 19.5 - 2
W = 17.5
:
:
Confirm this in the original perimeter formula
2(19.5) + 2(17.5) =
39 + 35 = 74
