The height of trapezoid is 7km.

Step-by-step explanation:

Given that the area of trapezoid formula is A = 1/2×(a+b)×h where a and b represents the length and h is the height. By substituing the values, you are able to find the height :

$area = \frac{1}{2} \times (a + b) \times h$

Let a = 4km,

Let b = 8km,

Let area = 42km²,

$42 = \frac{1}{2} \times (4 + 8) \times h$

$42 = \frac{1}{2} \times 12 \times h$

$42 = 6 \times h$

6h = 42

$h = 7 \: km$
