The area of the trapezoid is [tex]\frac{1}{2}(b1+b2)*h[/tex]
- b1 ⇒ length of one of the bases ⇒ 3 km
- b2 ⇒ length of the other base ⇒ 5 km
- h ⇒ height of trapezoid ⇒ 9km
Therefore the area is:
[tex]\frac{1}{2}*(3+5)*9 =\frac{1}{2}*(8)*9=4*9=36km^2[/tex]
Area: 36 square kilometers
Hope that helps!
