Answer:
Height = 5 ft
Short base = 10 ft
Long base = 14 ft
Step-by-step explanation:
Let h = height, a = short base, b = long base.
From the question,
a = 2h
b = a + 4 = 2h + 4
The area of the trapezoid is given by . Thus,
or
or
We discard the negative value of h since it is a measurement and cannot be negative.
We are given
We can write it as
we can see that 2y is in first two terms
and -8 is in last two terms
so, we can factor it out
now, we can see that x+4 is common in both terms
so, we can factor it out
we can see that
x+4 is one of factor of terms
so, option-B..........Answer
