split the figure into 3 shapes and multiply from there
Answer:
2L + 2W = 88
L = W + 12
L = 28 feet & W = 16 feet
Step-by-step explanation:
2L + 2W = 88
[] The perimeter of a rectangle is length + length + width + width, shortned as 2(legnth) + 2(width) and since the perimeter of the garden is 88, this option works.
L = W + 12
[] The length is 12 feet longer than the width, so the width + 12 will equal the length
Solving:
{ 2L + 2W = 88
{ L = W + 12
[Plug-in] 2(W + 12) + 2W = 88
[Distribute] 2W + 24 + 2W = 88
[Combine like terms] 4W + 24 = 88
[Subtract 24 from both sides] 4W = 64
[Divide both sides by 4] W = 16
L = W + 12 -> L = (16) + 12 -> L = 28
