Math CentralQuandaries & Queries


Question from Lynn:

I have 2 lots that have mobile homes on them... I was told they were 100 x 200 lots.. I have tried to calculate it on here but was not able to understand how to exactly do it. I would like to know if I have a 1/2 acreage or exactly what the 2 lots are?

Hi Lynn,

You have to be careful when finding area. If the side lengths are 100 feet and 200 feet and the corners are all right angles then you can calculate the area as $100 \times 200 = 20,000$ square feet. If the corners are not right angles then you need more information to calculate the area, the angle measures or the length of a diagonal.

If the corners are right angles then you have 40,000 square feet of area. One acre is 43,560 square feet so your two lots come to almost an acre.
