Use the image to answer the question.
An illustration shows the outline of letter upper L. The thickness of the outline is 7, marked at both ends of the letter. The vertical side of the outline, on the right, measures 13 and the upper horizontal side of the outline measures 15.
Find the area of the polygon in square units.
To find the area of the polygon, we first need to find the area of the entire rectangle and then subtract the area of the L-shaped cutout.
The area of the entire rectangle is:
Area = length x width
Area = 13 x 15
Area = 195 square units
Now we need to find the area of the L-shaped cutout. We can do this by finding the area of the larger rectangle formed by the L, and then subtracting the area of the smaller rectangle within the L.
The area of the larger rectangle is:
Area = (13 x 15) - (7 x 13)
Area = 195 - 91
Area = 104 square units
Therefore, the area of the L-shaped cutout is 104 square units.
