The length of a rectangle is 3 cm longer than its width.

If the perimeter of the rectangle is 54 cm, find its length and width.

Length = 28.5

Width = 25.5

length=15cmwidth=12cm

Step-by-step explanation:

solution2[l+w] is the formula of getting perimeter of a rectanglelet width be=xlength=x+3 since its longer than width2[x+3+x]=54 cm2[x+x+3]=54 cm2[2x+3]=54 cm4x+6=54 cm4x=54_64x=48 divide both side by 4x=12 cmwhere x is width = 12 cmlength is x+3 where12+3 = 15cm
