Sagot :

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

[tex]P=(5+2+2+2+1+1+1+2)(5ft)[/tex][tex]P=16(1in5tf)=80ft[/tex]

For the area we will divide the figure as follow:

The total area will be:

[tex]A=A_a+A_b[/tex]

We find the are of a rectangle by:

[tex]A=h\cdot b[/tex]

Where h is height and b is base

Then:

[tex]A_a=5\cdot2=10[/tex][tex]A_b=2\cdot1=2[/tex]

Then the total area is:

[tex]A=10+2=12^{\doubleprime}[/tex]

In feets:

[tex]12(5ft)=60ft^2[/tex]
