The length and width of a square by definition are of equal length.
The area (A) of a square = d2, where d is the length of one side.
If the area is known, then the length of the side of a square, d = √A (square root of A).
== 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 find the area (square feet) of a room, multiply the length by the width. 10 feet x 20 feet = 200 square feet.
i think you find the square root of the area. that's the length and the width, so you multiply it.
You would find the area by multiplying the width by the length, so the area would be 216 square feet.
If you only have square feet, you won't be able to find the height, unless you're mistaking height for length. Area in square feet of a quadrilateral is width times length. To find the length, divide the area by the width.
Length times the width
width=16 and length=20
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.
306 square feet. Multiply length by width - the result is the area in square feet.
If the room is rectangular - the usual case - multiply the length times the width. If length and width are in meters, the area will be in square meters; if length and width are in feet, the area will be in square feet, etc.
To find the area (in square feet) multiply the length times the width A = L x W = 4 x 3.5 = 14 square feet
Multiply length times width.
== 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.
11 and 5
Area is length times width: 140 square feet.
The width is 16 feet and the length is 20 feet and so 16*20 = 320 square feet
