b) 2.25 ft.
To solve for the base length, we need to divide 4.5 by 2:
4.5 = 2b
b = 4.5 / 2
b = 2.25
So, the base length is 2.25 ft.
An illustration shows a parallelogram turned so it rests on one corner. The area measures 4 point 5 square feet. The vertical height is indicated by a dashed perpendicular line from the angle on the right side to the opposite base and measures 2 feet. The length of the base is labeled with a question mark for the number of feet. Solve the equation 4.5=2b to find the base of the window in the shape of a parallelogram. What is the base length?
a)2.5 ft.
b)2.25 ft.
c)6.5 ft.
d)9 ft.
