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 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 perimeter of a rectangle with a length of three eighths and breadth of two thirds?
Perimeter = (length+breadth) times 2 = (3 + 3/8) x 2 = 66/8 = 63/4
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.
The length of a rectangle is three times its width If the area of the rectangle is 108yd2 find its perimeter?
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.
The perimeter of a rectangle is 28 inches if the length of the rectangle is three inches more than three times the width find the dimensions?
L + W = 28/2 = 14 L = 3 + 3W, so 3 + 3W + W = 14 ie 4W = 11 so width is 2¾" and length is 11¼"

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)
