He length of a rectangle is three times its width. If the area of the rectangle is 192 m2 find its perimeter.?
64 meters
The perimeter of a rectangle is 22 ft a right triangle inside the rectangle has a perimeter of 12 ft it's hypotenuse is 5 ft one side of the triangle is half the length of the rect solve all length?
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 length of a rectangle is 3 inches more than three times the width The perimeter is 78 inches Find the length and width?
Width = 9 inches Length = 30 inches
We are interested in the dimensions of a certain rectangle. This rectangle has length twice the side of the square and width three units less than its sides of this square. If the two areas are equal?
The rectangle is 12 units by 3 units.
The length of a rectangle is three times its width If the area of the rectangle is 147 what is its perimeter?
Write a a series of equations as follows p=2l+2w (formula for perimeter) a=l*w (Formula for area) l=3w (fact given in the question) a=147 (fact given in hte question) We don't currently have enough information to solve the perimeter formula for this rectangle, so we begin with the area formula to get more information. By substituteing 147 for the variable a and 3w for the variable l, we arrive at this equation: 147=w*3w With only one variable, we can solve this equation by isolating w on one side as follows 147=3w2(Multiply w by w to combine like terms) 147/3=3w2/3 (divide both sides by 3) 49=w2 sqrt49=sqrtw2(square root of both sides) 7=w We now know that the width of the rectangle is 7. We also know that the length is three times that, which is 21. We can substitute these values into the perimeter eequation as follows: p=(2*7)+(2*21) p=14+42 p=56 The perimeter of the rectangle is 56
The length of a rectangle is equal to three times its width if the perimeter is equal to 168 feet what is the length of the rectangle?
63 feet
The length of a rectangle is three times its width If the perimeter of the rectangle is 486in2 what is its area?
the length is equal to 160,083
The length of a rectangle is three times its width If the perimeter of the rectangle is 48?
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.
A rectangle has a length three times its width The perimeter is 68?
Width: 8.5 Length: 25.5
What is an expression for the perimeter of a rectangle that has a length which is three times its width?
call width x so length is 3x perimeter is (2*length)+(2*width) so perimeter is 8x

The length of a rectangle is three times its widthif the perimeter is equal to 144 feet what is the length of the rectangle?
L + W = P/2 = 72 feet L = 3W so L = 3/4 x 72 = 54 feet
What is the perimeter of a shape that has a side length of three and two fifths and another that is six and one eighths?
If it is a rectangle then: 2*(3.4+6.125) = 19.05 which is its perimeter
The perimeter of an equilateral figure can be found by multiplying the number of sides by the length of one side?
This is true. A square, which has four equal sides, will have a perimeter equal to four times the length of a single side.An equilateral triangle, which has three equal sides, will have a perimeter equal to three times the length of a single side.Any regular polygon contains all sides of the same length, therefore, the perimeter of a shape with a certain number of sides will be equal to the length of one side multiplied by the number of sides.
The length of a rectangle is three times its width and the area of the rectangle is 192ft squared what is its perimeter?
Area = 8*24 =192 square feet Perimeter = 24+24+8+8 = 64 feet
What is the relationship between the length and width that will provide the largest area of a three sided rectangle?
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.
