A square scrapbook page has a perimeter of (8x plus 20) inches. What is the length of one side of the scrapbook page?
2x + 5
The shorter side of a rectangle has a length of x inches the longer side has a lenght of 2x-1 in If the perimeter is 58 in find the length of the sides?
shorter side = 10 longer side = 19
How do you find the perimeter of 2x and 3x?
(2x x 3x) x 2 = 12x (2x times 3x times 2)
What is the area of a rectangle that has a length of 7.9 cm and a perimeter of 26.8 cm?
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
What is the perimeter of a triangle whose side lengths are x2 4 2x-1 and 5x?
Add them all together.
Why does the perimeter of a square double when you double the sides of a square?
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
What is a variable expression for the perimeter of the square with side 2x plus 1?
Perimeter of a square = 4 * sideP = 4 * (2x +1)P = 8x + 4
What is the perimeter of the of the square with side 2x and x plus 25?
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.
The side length of a square is 2x plus 3which expression represents the perimeter of the square?
4(2x+3) [there's 4 equal sides] 4(2x)+4(3) 8x+12
What is the perimeter of the square in terms of x the length of each side is 2x-1in?

If the perimeter of a square is 8x plus 6 what is its area?
Each side of the square is 2x+1.5 and its area is (2x+1.5) squared
How does the perimeter and area of a square change when its dimensions change?
A 3 x 3 square has perimeter 12 and area 9 A 6 x 6 square has perimeter 24 and area 36 Double the dimensions, double the perimeter, quadruple the area. Mathematically, a square with side x has a perimeter of 4x and an area of x2 Doubled, a square with side 2x has a perimeter of 8x and an area of 4x2
A square scrapbook page has a perimeter of (8x plus 20) inches. What is the length of one side of the scrapbook page?
2x + 5
What is the perimeter of the rectangle that is 0.9 square units?
There is no single answer to that The rectangle could be 0.9 by 1, giving a perimeter of 2x(0.9+1)=3.8 Or it could be 0.45 by 2, giving it a perimeter of 2x(0.45+2)=4.9 The minimum perimeter is when it is a square. The square root of 0.9 is approx 0.94868, so the perimeter would be approx 3.7947
How does doubling the each dimension of square affect the perimeter and the area of the square?
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.
How do you find the perimeter of a triangle with sides like 2x and 5x and 6x?
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
What is the perimeter of a square whose sides are 2x-1?
