The perimeter of a rectangle = 2 x (length + width) = 2 x (12 + 8) = 2 x 20 = 40 inches
The length of the rectangle is 27 meters and the width is 19 meters.
Let x = width of the box. We know that the length = 3x, and that the perimeter is 2*length + 2*width, thus we have the equation 2*(3x) + 2*x = 64 => 6x+2x = 64 Combining like terms: => 8x = 64 Solving for x by dividing both sides by 8: x=8 Thus we know that the width is 8, and length = 3*x =3*8 = 24 Area = width*length = 8*24 = 192
The dimensions work out as length 15 units and width 8 units Check: 2*(15+8) = 46 units which is its perimeter
