The area of a rectangle is the product of its length and width.
If a rectangle has a length L units and a width of W units, then
Area = L × W squared units.
Ethan is painting his deck. The deck was built around a tree,
So, there is a square hole in the deck that is 4 ft by 4 ft.
The area of the whole deck.
Area of rectangle = length x width
A = 29 x 13
A = 377
Now we need the area of the cut-out portion.
Area of square = side x side
A = 4 x 4
A = 16
Now subtract the area that was cut out from the area of the whole deck.
= 377 - 16
= 361 square feet
