Answer:
168 ft
Step-by-step explanation:
To calculate the area of a parallelogram, the formula is Area=base*height
In this case, the base is 14ft and the height is 12ft
so,
14ft*12ft=168ft^2
He needs 168ft or fabric to cover the area

Answer:
(x + 9)² = 36
Step-by-step explanation:
Given
x² + 18x + 57 = 12 ( subtract 57 from both sides )
x² + 18x = - 45
To complete the square
add ( half the coefficient of the x- term)² to both sides
x² + 2(9)x + 81 = - 45 + 81
(x + 9)² = 36
