Answer:

Perimeter = 56

Area = 196

Step-by-step explanation:

We use the Pythagorean theorem to calculate the half-length of the sides (a):

  • a² + a² = (7√2)²
  • 2a² = 7² * 2
  • 2a² = 98
  • a = 7

Half of a side is 7, meaning that the full length is 14.

With that in mind we can calculate the perimeter and area:

  • Perimeter = 14 * 4 = 56
  • Area = 14² = 196
