Answer:

P = [tex]\frac{28\sqrt{2} }{2}[/tex] units

A = 24.5 [tex]unit^{2}[/tex]

Step-by-step explanation:

Length of one side

sin [tex]45^{o}[/tex] = [tex]\frac{x}{7}[/tex]

7sin [tex]45^{o}[/tex]= x

7([tex]\frac{\sqrt{2} }{2}[/tex])= x

[tex]\frac{7\sqrt{2} }{2}[/tex] = x

Perimeter = 4([tex]\frac{7\sqrt{2} }{2}[/tex]) = [tex]\frac{28\sqrt{2} }{2}[/tex]

Area = ([tex]\frac{7\sqrt{2} }{2}[/tex])([tex]\frac{7\sqrt{2} }{2}[/tex]) = [tex]\frac{98}{4}[/tex] =24.5
