    Use the formula for the area of the trapezoid.

    What is the measurements for your trapezoid?

    a = base, b = base, and h = height

    Length of the bases, and h is the height, to answer the question. How many square feet of grass are there on a trapezoid field with a height of 175ft and the bases of 125ft and 81ft

    where A is area b1 and b2 ar the ^^length of the bases. (it's before that post.

    Alrighty your overall area equals A = 18,025.

    Not entirely. That's why I'm confused.

    okay so, a is your "top base" or the top measure of your trapezoid so the smallest measurement for the bases is what you'll plug in for a base.

    because "b" is always the bottom of your trapezoid.

    \[\frac{ 81 }{ 125 }\] is this correct?

    so 81+125?

    The equation for a trapezoid is a + b divided by 2 = h

  28. anonymous

    Yes! so now our equation looks like this: 81 + 125 _________ = h 2

    Your equation right now if you plugged in h = 175

  36. anonymous

    should look like this: 8 + 125 ________ = 175 2

    okay. oh wait. I just rechecked the equation. its 75 not 175. Does the equation still stay the same?

    Yes, so now we just want to plug in 75 for h instead of 175
