Answer:
Area = 49 ft²
Step-by-step explanation:
The formula for area of a parallelogram is A = bh, where b is the base, and h is the height. Here, the base is given and the height is 4 times the length of the base
Here b = 3 1/2, and h = 4(3 1/2) = 14
3 1/2 becomes 7/2 as an improper fraction, 4(7/2) = 28/2 = 14
So the area is
A = 14(3 1/2)
A = 14(7/2)
A = 98/2
A = 49 ft²

Step-by-step explanation:

Answer:
(4-1)•n=n•(4-1)
Step-by-step explanation:
It should equal each other so no matter what n equals it will equal each other :3
The circumference of a circle can be found using the equation 2 π r
(2)(3.14)(4.5) = 28.26 (or 28 13/50 if you need it in fractions)
D, hope this is right! :)
