Answer:
1 9/16 square feet or 1.5625 square feet
Step-by-step explanation:
Area of a rectangle is Length x Width
First convert 2 1/2 into a number that is just a fraction.
2 = 4/2 so 4/2 + 1/2 = 5/2
Now you can multiply the two fractions to find the area.
area = 5 5 25
-- x -- = -----
8 2 16
To simplify this, you know 16/16 = 1 so subtract 16 from the numerator which leaves 9/16
Your answer will be 1 and 9/16
Let h(t)= 0 (because when it reaches the ground h=0)
0=-16t^2+116
16t^2=116
divide both sides by 16
t^2= 7.25
square root both sides to find t
t=2.69sec
