2x + 5
shorter side = 10 longer side = 19
(2x x 3x) x 2 = 12x (2x times 3x times 2)
Let the width be x: Perimeter = 2(7.9+x) = 26.8 15.8+2x = 26.8 2x = 26.8-15.8 2x = 11 x = 5.5 cm Area = 5.5*7.9 = 43.45 square cm
Add them all together.
The perimeter is the sum of the sides. So if a square has a side of length 1, its perimeter is 1+1+1=1 = 4 If a square has a side doubled to length 2, its perimeter is 2+2+2+2 = 8, or double what it was before. Mathematically, if each side is length x it perimeter is x + x + x = X = 4x If each side is length 2x, its perimeter is 2x +2x+2x+2x = 8x
Perimeter of a square = 4 * sideP = 4 * (2x +1)P = 8x + 4
I'm assuming that you meant the perimeter of a rectangle, not a square...The equation for the perimeter would be 2x + 2x + x + 25 + x + 25.You combine the like terms, and get 6x + 50.So the answer is 6x + 50.
4(2x+3) [there's 4 equal sides] 4(2x)+4(3) 8x+12

To find the perimeter of a shape, you need to know its dimensions and the number of sides. If you are referring to a single side length of ( 2x - 1 ) for a polygon, such as a rectangle, you would need the lengths of the other sides to calculate the perimeter. If it's a square, the perimeter would be ( 4(2x - 1) = 8x - 4 ). Please provide additional details about the shape for a more accurate answer.
Each side of the square is 2x+1.5 and its area is (2x+1.5) squared
2x + 5
If you double the dimensions, then the perimeter is doubled. However, the area is quadrupled. For example, let's say that a side of a square is x units. The perimeter would be 4x, and the area x2. Now, let's double the dimension into 2x. Now, the perimeter is 8x, and the area is 4x2. As you can see, the perimeter is doubled and the area is quadrupled.
To find the perimeter of a triangle you have to add up all the sides. So to find the perimeter of this triangle you just add 2x+5x+6x=13x. To find the actual perimeter you would have to know what x equals
