Answer:
Base = 6 feet
Step-by-step explanation:
Area of Triangle =
<u><em>For finding Base:</em></u>
Base =
Where Area = 15, Height = 5
Base = 2*3
The base is 6 feet long.,
Area of a triangle = 1/2 * base * height so we have
1/2 b h = 15
1/2 b * 5 = 15
2.5 b = 14
b = 15/2.5
b = 6 feet.

A ∪ B is the set of all elements that are in either the Blue or Green circles, or both. The number of its elements is ...
8 + 7 + 14 + 6 + 1 + 8 = 44
n(A∪B) = 44
