The perimeter of a rectangle is 128 cm. The width is 3 times the length. What are the dimensions of the rectangle?

Step-by-step explanation:

Perimeter of the rectangle= 128

Let, the Length of the rectangle be 'L'

Width=3*L

Perimeter of the rectangle =2(Length+width)

            Width=4*L= 4*16= 64

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
