Answer:

Step-by-step explanation:
The area of a triangle with base
and height
is given by
. In the trapezoid, the two triangles share a height of 6, however one has a base of 6 and the other has a base of 8.
Area of smaller triangle (triangle on the left): 
Area of larger triangle (triangle on the right): 
Therefore, the sum of their areas are 
The thousandth's decimal mark is the third number behind the decimal point which in this case it would be 9. To round to the nearest thousandths you need to look at the number behind 9 which is 1. 1 is less than 5 so you wouldn't round to 10. The answer is .009!
Ok so we know that the total perimeter of the rectangle is 48m.
We also know that to get the perimeter, it is the sum of two lengths and two widths.
Therefore 2L + 2W = 48
However, we also know that the width is 2m less than the length, so the above equation can be rewritten as:
2L + 2(L-2) = 48
We can simplify this to make it
4L - 4 = 48
So 4L = 52
Hence L = 13.
We know that the width is 13-2, so the width is 11.
So the length is 13m and the width is 11m
Hope this helped
