Not enough information. You need to know what sort of figure you are talking about - for example a rectangle, an ellipse, the surface of a rectangular block, etc.
A=L(W) A= 10(3) A= 30ft2
21 ft.

Yes, using two 3ft x 3ft tiles.
yes.
It is not possible to determine the area of a quadrilateral given only the length of its four sides.
A=L(W) A= 10(3) A= 30ft2
21 ft.
It is not possible to provide an answer. Four linear measurements suggest that the figure is a quadrilateral of some sort. Unfortunately, information about the lengths of the sides is not enough to uniquely identify the shape and so the area cannot be determined. In order to see why the area cannot be determined, consider a rectangle with sides of 1 cm, 2cm, 1 cm and 2 cm. Clearly, its area is 1*2 = 2 cm2. However, the rectangle can be "distorted" into a parallelogram, with the same sides, but whose vertical height (and so its area) is reduced to 0!

It is: 10*7*3 = 210 cubic feet
Volume: pi*32*10 = 90*pi cubic feet
Yes, using two 3ft x 3ft tiles.
To find the area of 3ft by 1ft, you multiply the two. So the area is 3 square feet.
yes.
66 square feet
Yes we can with the help of 2 tiles placed side-by-side.
