Question

write a general rule to find a perimeter of square ​

Answer 1

Multiply the side length by 4 to find the perimeter.

Take the side length s you just calculated and plug it into the perimeter formula, P = 4s. The result will be the perimeter of your square! For the square with area 20 and side length 4.472, the perimeter P = 4 * 4.472, or 17.888.

Answer 2

$\huge \mid{ \underline{ \overline{ \underline{\overline \pink{\bold{ \: \: Aɴsᴡᴇʀ \: \: } }}} }}\mid$

• perimeter of square = 4 × side
• perimeter of square = side + side + side + side
