it would be
396ft=
(x+8)ft=xft+8ft
(x+4)ft=xft+4ft
Square footage is two-dimensional, the product of length times width. Unless the shape is a square, the area by itself is not sufficient to definitively ascertain the dimensions.
== Area of Room== To find the area in square feet of a room, multiply the length (in feet) by the width (in feet). Since you provided three dimensions, perhaps you wished to find the volume in cubic feet. To do so, multiply length, width, and height. Be sure your units are consistent.
to calculate square feet, you find the dimensions of a room and multiply them p.s. the dimensions have to be in feet p.s.s. the dimensions are the length and width of the room p.s.s.s. the length is sideways, and the width is up and down.
The dimensions are: length = 15 inches and width = 7 inches Check: 15*7 = 105 square inches
The length and width of a square are equal. Thus, find the square root of the area and the answer = length= width.
If the dimensions of the rectangle are in feet, the perimeter will be in feet as well. The area will be in square feet. The area is length x width. The perimeter is 2 x (length + width) or 2 x length + 2 x width.
Unless it's a square, you'd have to know either the width or the length.
length times width
Find the length and width of the shape
For a rectangle or square, Area = Length * Width So Length = Area / Width.
length, width, height
The dimensions are W and W+M where W is the width.
