I believe the right equation for determining the area of a trapezoid is as below,
A = h(a + b)/2

To determine the expression for b which is the length of one of its bases, we multiply the equation by 2.

2A = h(a + b)

Then, divide both sides of the equation by h,

2A/h = a + b

Then, subtract a from both sides of the equation,
2A/h - a = b

Lastly, interchange the sides of the equation to reveal the answer.
<em> </em>
<em> b = 2A/h - a </em>

What time is 71/2 hours before 2:12 am?

meriva

ANSWER: 1:42 PM

First find how many hours 71/2 hours is. Half of 71 is 35.5. Do one day back... So 35.5 hour becomes 11.5 hours and 2:12 AM still stays the same. Now take away 30 min (0.5) from 11.5 hours and from 2:12 AM. Now the numbers are 11 hours and 1:42 AM. Subtract 1 hour from both amounts, 10.5 hours and 12:42 PM. Now, subtract 11 hours from both amounts again. 0 hours left and 1:42 PM.
