Answer:
12.808 meter is the length should Rickey use for the mural.
Step-by-step explanation:
Area of the mural = A =
Length of the mural = l
Width of the mural = w
l = 5 + 2w
Area of the rectangle = l × w
Solving above equation with the help of Completing squares method:
w = 3.904 m (accept)
w = -6.404 m (reject)
l = (5 + 2w)m = 5 + 2 × (3.904) m= 12.808 m
12.808 meter is the length should Rickey use for the mural.
