When a square paper is folded vertically to form a rectangle with a perimeter of 39 inches, the length of the rectangle is 19.5 inches (half of the perimeter). Since the length of the rectangle is the same as the side length of the original square, the area of the original square can be calculated as the square of the side length, which is 19.5 inches squared, equaling 380.25 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.
The perimeter of a rectangle can be calculated by adding up the lengths of all its sides. In this case, the rectangle is 7 inches by 8 inches, so its perimeter would be 2(7) + 2(8) = 14 + 16 = 30 inches.
The perimeter is 35.78 inches.
112 inches
Six inches
Perimeter = 32 inches. Area = 55 square inches.
The length of a rectangle is 8 inches. The width of the rectangle is 4 inches. What is the perimeter of the rectangle in inches?
If you mean a 3 inches by 4 inches rectangle then its perimeter is 14 inches
The perimeter of a rectangle can be calculated by adding up the lengths of all its sides. In this case, the rectangle is 7 inches by 8 inches, so its perimeter would be 2(7) + 2(8) = 14 + 16 = 30 inches.
the area of a rectangleis 100 square inches. The perimeter of the rectangle is 40 inches. A second rectangle has the same area but a different perimeter. Is the secind rectangle a square? Explain why or why not.
The perimeter would be 36 inches.
yes
The perimeter is 60 inches
Length of rectangle is 5 inches and its width is 4 inches Check: 2*(5+4) = 18 inches which is its perimeter
28 inches
32 inches
The perimeter of a rectangle = 2 x (length + width) = 2 x (12 + 8) = 2 x 20 = 40 inches
16 inches
