Answer:

465.75 or 465.8 rounded to the nearest tenth

Step-by-step explanation:

You would multiply 16.2 and 14.5 and divide by 2 to get 117.45. You then multiply by 3 for the 3 sides to get 352.35. Lastly, to find the area of the base you would need to multiply 16.2 and 14 and divide it by two to get 113.4. Add it with the 3 sides and you get 465.75.

The coordinates of the points below represents the vertics of a rectangle

Tanya [424]

Not sure what the question is, but I'm guessing you want to find out the area of the rectangle.

The distance between points P and Q is 4.

The distance between points Q and R is 3.

So the area is 3 * 4 = 12.
