Answer:

21ft

Step-by-step explanation:

First, cut the figure into two rectangles. Thus:

1st rectangle: L=5, W=3

1st rectangle: L=5, W=3 2nd rectangle: L=2, W=3

Then, get the area of the two rectangles...

1st rectangle:

A = Length × Width

= 5 × 3

= 15ft

2nd rectangle:

A = Length × Width

= 2 × 3

= 6ft

And lastly, add the area of the two rectangles to get the area othe whole figure.

15ft + 6ft = 21th
