Answer:
The other base is 8 feet.
Step-by-step explanation:
You need to recall the area of a trapezoid equation:
[tex]\frac{a + b}{2} * h[/tex]
We need to work back, so we need to divide the area by 6:
60 ÷ 6 = [tex]\frac{a + b}{2}[/tex] = 10
Then we need to multiply this by two to find a + b value:
10 x 2 = a + b
20 = a + b
Beause we know the value of a, which is 12, we can factor this in:
20 = 12 + b
Move the +12 over to the other side, making it a negative:
20 - 12 = b
8 = b
So the other base is 8 feet!
Hope this helps!
