3 sq. ft. or 432 sq. in.
Area of room = width * length = (2x-1)*(7x+3) = 14x2 + 6x - 7x - 3 = 14x2 - x - 3 sq feet
The answer will depend on the shape: whether it is a cuboid or an ellipsoid, or just a large shapeless blob.
Area = 5.5*3 sq ft = 16.5 sq ft
If you use a depth of 3 inches, that area will be about 16.2 cubic yards (around 20.785 tons) of gravel.
16 feet long and 3 feet wide is 4.46 square meters.

Find the area of a rectangle that is 3 feet wide and 5 feet long.
A = LxW A = 3x6 A = 18 ft squared.
2 feet wide and 300 feet long, 3 feet wide and 200 feet long. 6 feet wide and 100 feet long. 10 feet wide and 60 feet long 20 feet wide and 30 feet long. I could go on and on and on and on and on and on and on.
3 sq. ft. or 432 sq. in.
The volume of a cylinder 8 feet long by 3 feet wide is: 56.5 cubic feet.
If it's rectangular, just multiply the length times the width.
225 square feet. To calculate square feet simply multiply length by width - the result is the area in square feet.
Area = 3*45 = 135 square feet. Perimeter = 2*(3 + 45) = 2*48 = 96 feet.
