The perimeter is determine as the add of the sides of the figure. In this case:


P=(5+2+2+2+1+1+1+2)(5ft)
P=16(1in5tf)=80ft

For the area we will divide the figure as follow:

The total area will be:


A=A_a+A_b

We find the are of a rectangle by:


A=h\cdot b

Where h is height and b is base

Then:


A_a=5\cdot2=10
A_b=2\cdot1=2

Then the total area is:


A=10+2=12^(\doubleprime)

In feets:


12(5ft)=60ft^2
