The only way for you to get an answer is by doing $5.25x2=$10.5 and $3.50x3=$10.50
Answer:
The perimeter of the square is 16 √ 5
The area of the square is 8√5
Step-by-step explanation:
To solve this you first need to solve 4√5 which is 8.94. This made the perimeter 35.76 which is equaled to 16√5. The area is 17.88 which is the same as 8√5.
