This problem wants us to find the area of the figure into round to the nearest tenth if necessary.
00:04
And the way we're going to figure out this area is to kind of break it into two shapes.
00:08
We're going to find the area of our first shape here, that is the shape of a rectangle, by multiplying its length times the width.
00:16
And then for our top shape, we will find the area there by realizing that's a trapezoid, and the area formula for the trapezoid is our two bases added up and divided by two, and then that value times the height of the trapezoid.
00:29
So we will deal with the easier problem first, just our length times our width.
00:33
Our length of 18 miles for the bottom base of our trapezoid and also the top length of our rectangle will be our length times our width of 5 miles.
00:41
We'll give us an area for the first shape or our rectangle shape of 90 miles squared from 18 times 5.
00:48
And now we'll combine that with our area from our trapezoid.
00:52
In our area for the trapezoid, we know the formula of 12 plus 18 for our two bases added up.
00:59
Divided by two, and then times our height...
