Awindow shaped like a parallelogram has an area of 18 1/3 square feet the height of the window is 3 1/3 ft how long is the base of the window

Formula for area of parallelogram:
A= Base x Height
Here Area, A= 18 1/3 ft²
Height, H=3 1/3 ft
Convert the mixed number into improper fraction.
18 1/3 = 55/3
and 3 1/3= 10/3
Put values in formula to get the length of base.
55/3=B x 10/3
Multiply both sides by 3.
55=10B
Divide both sides by 10.
55/10=B
or
B=11/2 ft
or
B= 5 1/2 ft

Base of window is 11/2 ft or 5 1/2ft

Don’t know sorry about that
