Q:
a trapezoid with base measure of 23 km and 29km an area of 390km . find the height of the trapezoid.
Accepted Solution
A:
Hello!
To find the area of a trapezoid you use the equation
[tex]A = \frac{a+b}{2} h[/tex]
Put in the values you know
[tex]390 = \frac{23+29}{2} h[/tex]
Add
[tex]390 = \frac{52}{2} h[/tex]
Divide
[tex]390 = 26 * h[/tex]
Divide both sides by 26
15 = h
The answer is 15km
Hope this helps!
