135
To find the area of a rectangle, you need to multiply its length by its width. In this case, the length of the portrait is 13.5 inches and the width is 10 inches.
The formula for the area of a rectangle is:
Area = Length × Width
Plugging in the given values, we have:
Area = 13.5 inches × 10 inches
To multiply these two numbers, simply multiply the numbers together:
Area = 135 square inches
Therefore, the area of the portrait is 135 square inches.
