Arectangular 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.
