A rectangular garden has a perimeter of 100 feet. The length of the garden is 20 feet greater than twice the width. The system of linear equations shown below represents this situation, where ℓ is the length of the garden and w is its width. Find the length and width of the garden. lbrace 2ℓ + 2w = 100 ℓ − 2w = 20 The length of the garden is feet and the width is feet.
