A rectangle is three times as long as it’s wired the perimeter 60 cm find the dimensions of the rectangle a round to the nearest 10th if necessary

  width:  7.5

  length: 22.5

Step-by-step explanation:

width:  x

length: 3x

Perimeter = 2L + 2W

60 = 2(3x) + 2x

60 = 6x + 2x

60 = 8x

x = 7.5

width:  x = 7.5

length: 3x = 3(7.5) = 22.5

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
