Question

There is a trapezoid that has an area of 25. If one of its bases is 4 and its other base is 6, what must its height be?

Answer 1

We know that formula to solve for the area of a trapezoid is A=(a+b)/2+h. So, the formula to find the height would be 2*[A/(a+b)].
2*[A/(a+b)] Substitute the values for the variables
2*[25/(6+4)] Solve the parentheses
2*(25/10)
2*2.5=5
The height must be 5.
