I assume the measurements shown in the question is in inches?
Therefore: 13 × 5.5 = 71.5 square inches
To find the area of a rectangle, you multiply its length by its width. For an 11x13 rectangle, the area is calculated as (11 \times 13 = 143) square inches. Therefore, the area of an 11x13 rectangle is 143 square inches.
The area of rectangle is : 78.0
325 square inches
9 times 13 = 117 square inches
Its area is 13 times 12 = 156 square inches.
13I2 square inches.
If that's a rectangle, just multiply length x width.
9 x 13 = 117 square inches
169 square inches. Folding the square in half leaves 2 edges of the original side length and two of half the side length. Therefore: perimeter = side + 1/2 side + side + 1/2 side = 3 sides ⇒ 3 sides = 39 inches ⇒ 1 side = 39 inches ÷ 3 = 13 inches ⇒ area_original_square = 13 inches x 13 inches = 169 square inches.
117 square inches (13 x 9 = 117)
11' x 13' = 20,592 square inches.
14,976 square inches.
