Answer:
225 km^2
Step-by-step explanation:
Area of a trapezoid: ((Base 1 + Base 2) x h) / 2
(11 + 19) x 15 / 2
= 225 km^2
=(1/2) * 2 * 3.2 + (1/2) *2 * 3.2 + (1/2) * 2 * 4 + (1/2) * 2 * 4
= 2 * 3.2 + 2 * 4
= 2 * (3.2 + 4)
= 2 * 7.2
= 14.4 sq feet
2 * 14.4 = 28.8 sq feet
Answer:
1.5
Step-by-step explanation:
35
area of triangle is (base X height)/2
so it would be (14 X 5)/2
which is 70/2
which is 35
