Answer:
14 m²
Step-by-step explanation:
the height of the triangle is 3 m and the base is 4 m. 3 times 4 is 12 but then you have to half that so the area of the triangle is 6 m. The area of the rectangle is 2 times 4 which is 8. 8 plus 6 is 14. So 14 is your answer.

Answer:
The height of the cone is h = 27
Step-by-step explanation:
<u>Formula:</u>-
Step 1:-
The volume of the cone is 
Given volume is V= 45 in^ 3
Given base of the cone is B= 5 in^2
<u>Step 2</u>:-
by using formula, we get solution

cross multiplication, we get

now simplification, the height of the cone is h = 27
