Conventionally the shorter measure is the width, so the 6 ft would be taken to be the width.
However, it does not have to be, for example the width of a window is the distance from side to side regardless of the height of the window - with a short but wide window the width would be the longer measurement.
(width + 6) feet, of course!
Width = 16 feet Length = 38 feet
6 feet (5 + 5 + 6 + 6 = 22)
You have provided the length and width of the boards but only the width (height) of whatever you wish to board. there is no information on its length and consequently, the question cannot be answered.
It is (W - 6) feet where W is the width measured in feet.
Assuming that you mean how many square feet is 6 feet x 8 feet, the answer is 48 sq. ft. (6x8=48)
(width + 6) feet, of course!
The width is 6 feet. The length is 8 feet.
48 feet. You just multiply the width times the length.
The area of the rectangle is 72 square feet
Area = Length * Width so Width = Area / Length = 72 sq feet / 12 feet = 72/12 feet = 6 feet.
Width = 6 feet Length = 24 feet
Width = 16 feet Length = 38 feet
The width is 10 feet and so 10*6 = 60 square feet
Width = four feet 6 inches, Length = 6 feet
11 and 5
Its width is 13 feet and 13*19 = 247 square feet
