Answer:
Area = 36 sq. units
Step-by-step explanation:
The 3 values you need to solve for the area are the top base length, bottom base length, and height.
Top base length = 7 . It's the distance between point A and B.
Bottom base length = 11. It's the distance between points C and D.
Height = 4. It's the perpendicular distance from the top to the bottom base.
The formula to solve the area of a trapezoid (or trapezium, I'm American) is:
A =
Put in the numbers above for the unknowns and you will get this:
A =
Simplify:
A=
A = 2(18)
A = 36
So the answer is 36. Hope I helped!
Answer:
Step-by-step explanation:
The equation that will model this situation will be of the form
where is the time in hours john has traveled since the gas station, and
is the distance.
Now we know that John has already traveled 20 miles when he is at the gas station, this means at ,
; or
Thus we have
.
Now we need to figure out
When John reaches home 2 hours later he notes that he has traveled 30 miles, which means he has traveled 30 - 20 = 10 miles; thus we have
Now we have the full equation:
