Because the area of a trapezoid is A= ((a+b)/2)h, where a is the length of the top, b is the length of the base, and h is the height, you plug that in to find your answer.
This trapezoid is sideways, but the top of it is 7m (which is a) and the base is 10 m (which is b), add a and b to get 17, A = ((17)/2)h
Now divide by 2 to get A = (8.5)h
Because the height is 9, A = (8.5)9 = 76.5
The area of the trapezoid alone is 76.5m
Answer:
$40
Step-by-step explanation:
we know that
The linear equation in slope intercept form i equal to
where
y is the amount of her mother's donation
x is the number of miles that Melissa walks
where
m is the slope
b is the y-intercept
In this problem
The slope is
The y-intercept is
substitute
so
For x=15 miles
substitute
The answer is 8
24/6 = 4
Then 4 x 2 = 8
