Okay, so you know that the diameters of each circle is 4, hence the radius is 2.

Perimeter: 4x (pi x 4) = 50.2654824574 feet

Area: 4 x (pi x 2^2) = 50.2654824574
50.2654824574 + 4x4 = 66.2654824574 feet squared

Hope I helped!

Hello,

Explanaisons:

Permeter is composed of 2 circles having a radius of 2 ft:
p=2*(2π*2)=8π≈25.1327... ft

Area is composed of a square which side is 4 ==>4*4=16 (ft²)
and 2 disks having for radius 2 : 2*π*2²=8π

Area=16+8π≈41,132741 (ft²)
