Word Problem

Okay, easy question here. But I'm terrible at math and just want to make sure I get this right.

A parcel of land is rectangular and measures 60' by 80'; there is a shed that measures 15' x 20' and a driveway that is 50' long and 10' wide. How much land area can be sampled, not including the shed and driveway? If one sample is to be collected every 500 sq. ft., how many samples will be collected?

Here's how I worked it out. Let me know if I screwed up.

60' x 80' = 4,800' total
15' x 20' = 300' (shed)
50' x 10' = 500' (driveway)

4,800' - 800' = 4,000'...total land area that can be sampled if one excludes the shed and driveway.

4,000'/500' = 8...the total number of samples collected if one sample is collected every 500'.

Re: Word Problem

You might just check your units for area.
