If the perimeter of a square is 80' then each side must be 20' in length. (4 x 20 = 80)
The area of a rectangle is obtained by multiplying the length by the width.
A square is a rectangle with all four sides of equal length therefore the area is two lengths multiplied together.
20 x 20 = 400 sq ft is thus the area of the square.

400 square feet.
It is: 4 times the square root of 80 which is about 35.777 feet to three decimal places.

They could be almost anything. A strip of land 1 foot by 4000 feet would have a perimeter of 8002 feet. A plot 50 x 80, still 4000 square feet, would have a perimeter of 260 feet.
To find the area of a rectangle, you multiply the length by the width. In this case, 40 feet multiplied by 80 feet equals 3200 square feet. So, there are 3200 square feet in a 40' by 80' area.
