Lucia is hoping that Angela will buy her a geometrically interesting piece of land on which he will build a mansion. Lucia has said that she will only buy the land if it costs less than $4.00 per square foot. The plot shown below is listed for $453,175. Is Angela going to be able to get this land? Explain how you found your answer.
There should also be an image if you search this question on open study! The numbers are 187.5ft, 225ft, 397.5ft, and 390 ft.
Is there a certain formula I would have to use for this question? I know I can't find the area since the sides are all different so would I use perimeter? Also, how would I check my answer to make sure it is correct?
The shape is also two trapezoids on top of each other, one upside down and the other upright.
two adjoining trapezoids produce a figure with six sides. You only give four lengths.
You will need to use the sides and the Pythagorean Theorem to determine the heights of the trapezoids.
Then it's easy, since you know the formula for the area of a trapezoid, given its bases and altitude.
