The perimeter of a rectangle is 18 feet and the area is 14 square feet what is the length and width?
*This is easily guessed but the albegraic solution uses two equations, perimeter and area.
Perimeter = twice the length plus twice the width = 2L + 2W
Area = length times width = L * W
P = 2L + 2W = 18
A = L * W = 14
2L = (18 - 2W) and L = (18 - 2W) / 2 so L = 9 - W
Substituting this value in the Area equation
A = L*W = (9 - W) * W = 14
The equation W2 - 9 W +14 = 0 has the solutions (W - 7)(W - 2) = 0
The dimensions must be 7 feet by 2 feet (either can be length or width).

What is a perimeter of a recangular?
Perimeter is Length + width x 2 or Length + length + width + width. This is perimeter for any shape including a rectangle. Perimeter of a rectangle is all sides added together for a rectangle.

What is the perimeter of a rectangle that is 1.6 meters long and 0.8 meters wide?

The perimeter of a rectangle is 72m the width of the rectangle is 16m what is the area of the rectangle?
To find the area of a rectangle, you need to know the formula: Area = length x width. Given that the perimeter is 72m and the width is 16m, we can calculate the length by using the formula for perimeter of a rectangle: Perimeter = 2(length + width). Substituting the values we have, 72 = 2(length + 16), which simplifies to length + 16 = 36. Therefore, the length of the rectangle is 20m. Finally, the area of the rectangle is 20m x 16m = 320 square meters.

What is the formula for the perimeter of a square and rectangle?
The perimeter of any rectangle is [ 2 x (length + width) ]. Since the length and width of a square are equal, the perimeter of a square is also [ 2 x (side + side) ] = (4 x side).
