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.
Answer: it would be 5

The answer is -10. I think about negative numbers on a number line with numbers being behind and in front of the zero. To check the answer you can imagine being on -10 and when it says to minus a number you always know that it’s going to go further into the negative. So -10-10 is -20.
square meter is the SI unit of area.
Answer:
y = 2x
Step-by-step explanation:
Given y is directly proportional to x then the equation relating them is
y = kx ← k is the constant of proportion
To find k use the condition when x = 4, y = 8, that is
8 = 4k ( divide both sides by 4 )
2 = k, thus
y = 2x ← equation of proportion
