call width x

so length is 3x

perimeter is (2*length)+(2*width)

so perimeter is 8x

the length is equal to 160,083

15 feet.

63 feet

Width: 8.5 Length: 25.5

64 meters

If it is a rectangle then: 2*(3.4+6.125) = 19.05 which is its perimeter

Area = 8*24 =192 square feet Perimeter = 24+24+8+8 = 64 feet

Perimeter = (length+breadth) times 2 = (3 + 3/8) x 2 = 66/8 = 63/4

The perimeter of that rectangle is 89.6875.

ok, i figured it out. the length of the triangle is 5, 4, 3. the four is 1/2 the length of one side of the rectangle. so the rectangle sides are 8, 8, 3, 3 (one three being one side of the rectangle as well)

The perimeter of a rectangle is equal to 2*length + 2* width. In this case, we will say 2x + 2y = p = 48. Since the length is equal to 3 times the width, the equation now becomes p = 6*y + 2*y, or just p = 8y. Now since p =48, y must equal 6. And since the length is three times the width (y), the length is 18.

l=3w Perimeter (p) = 2*(l+w) = 56 2*(3w+w)=56 2*4w=56 8w=56 w=7 inches l=3w = 3*7 = 21 inches

twice length + twice width = perimeter In this example, L= 3W 2(3W)+2(W)=64 8W=64 W=6 L =3W L=18 The dimensions of this rectangle are: 18 by 6

Width = 9 inches Length = 30 inches

That would be 3 x 9 inches.

The perimeter is the measure of length of the boundary of a 2-dimensional object. The most common mathematical objects in this category are squares, rectangles, circles and triangles. The perimeter of a square = 4d (where d is the length of 1 side) The perimeter of a rectangle = 2l + 2w (where l is the length and w is the width) The perimeter of a circle = 2πr (where π is the mathematical constant pi and r is the radius. The perimeter of a circle is better known as the circumference) The perimeter of a triangle is the total length of all three sides.

L + W = P/2 = 72 feet L = 3W so L = 3/4 x 72 = 54 feet

Well, L=6 and W=18If you do the math you get (6*2)+(18*2)=12+36=48Your final answer 48 yd. The perimeter is 48 yd.

5mm is NOT TRUE You find it by dividing it by 2

It will be three times the size. Each length will be multiplied by 3.. Perimeter = h+h+w+w if we multiply each by three then we get 3h+3H+3w+3w = 3P

There is no such thing as a three sided rectangle. They have four sides. Length and width of a rectangle being THE SAME (having a 1:1 ratio) will provide the largest area possible. In other words, for a given perimeter, a square is the largest rectangle. If you mean a triangle (which has three sides), then all sides being equal will still yield the largest area.

The rectangle is 9 inches wide X 27 inches long. Clue: width is X; length is 3 times width (3X). Perimeter is width plus length times two (X + 3X times 2 = 8X). 8X = 72; X = 9. 3X = 27. Proof: 9 + 9 (2sides) +27 + 27 (2 lengths) = 72.

L + W = 28/2 = 14 L = 3 + 3W, so 3 + 3W + W = 14 ie 4W = 11 so width is 2¾" and length is 11¼"

No you cannot. All that you can be certain of is that the width, W, is in the range 0 < W <= 3 and that the length, L satisfies W + L = 6 units.

A rectangle is a two dimensional object: height, width and length are three dimensions.
