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

Respuesta :

Answer:

  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
