To find the area of a trapezoid, you can use the formula A = ((base1 + base2) / 2) * height.
In this case, assuming 8 km is base 1, 4 km is base 2, and 12 km is the height, you can plug these values into the formula to find the area.
A = ((8 + 4) / 2) * 12
A = (12 / 2) * 12
A = 6 * 12
A = 72
So, the area of the trapezoid is 72 square kilometers.
Answer: Substitute into A = ½ (a + b) h
Step-by-step explanation:
The formula for calculating the area of a trapezoid is A = ½ (a + b) h,
so just substitute your values in.
I cannot substitute them in for you, since you haven't provided me with a clear picture of which values represent which length.
Hope this helps!
