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
