What is the area of a rectangle with a perimeter of 42cm?
You can't tell the area from knowing the perimeter. There are an infinite number of different rectangles, all with the same perimeter, that all have different areas. Here are a few rectangles that all have perimeters of 42. The last number after each one is its area: 1 cm by 20 cm . . . . . 20 square centimeters 2 x 19 . . . . . 38 3 x 18 . . . . . 54 4 x 17 . . . . . 68 5 x 16 . . . . . 80 10 x 11 . . . 110
What is the perimeter of square 6in by 13 in?
38 inch
One pair of corresponding sides of two similar polygons measures 12 and 15 The perimeter of the smaller polygon is 30 Find the perimeter of the larger?
The perimeter of the larger polygon will have the same ratio to the perimeter of the smaller as the ratio of the corresponding sides. Therefore, the larger polygon will have a perimeter of 30(15/12) = 37.5, or 38 to the justified number of significant digits stated.
The perimeter of a square is 152 what is the area of the square?
To find the area of a square, we need to know the length of one side. Since the perimeter of a square is the sum of all four sides, we can divide the perimeter by 4 to find the length of one side. In this case, 152 divided by 4 is 38, so each side of the square is 38 units long. To find the area of the square, we square the length of one side, so the area of the square is 38 squared, which equals 1444 square units.
What is the perimeter of 14 inches wide and 24 inches long?
Assuming it is rectangle, then the perimeter equal twice the summation of length and width. Answer = 2 x (14 + 24) = 2 x 38 = 76 inches
