Answer:
The area of Trapezoid is 21 square Kilometres.
Step-by-step explanation:
Given;
a = 5 km
b = 9 km
h = 3 km
To Find;
Area of Trapezoid = ?
Now,
Formula;
A = (a + b/2) × h
A = (5 + 9/2) × 3 km
A = (14/2) × 3 km
A = 7 × 3 km
A = 21 square Kilometres
Thus, The area of Trapezoid is 21 square Kilometres.
