Answer:
The height of the mural is 10.2 feet.
Step-by-step explanation:
The general formula for the area of a rectangle is A = LW, where A = area, W = width and L = length (height in this example). Since we know the values of both area and width, we can plug these numbers into the formula and solve for the missing variable 'L': 128.52 = 12.6L. Using inverse (opposite) operations to isolate the variable and solve, we would divide each side of the equation by 12.6: 128.52/12.6 = 12.6L/12.6 or L = 10.2. So, the height of the mural would be 10.2 feet.
