Question

I need help with this math

Answer 1

Perimeter = 56

Area = 196

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
