the perimeter of a rectangular painting is 314 cm. If the length of the painting is 99 cm, what is its length?

Respuesta :

Answer:

58 cm

Step-by-step explanation:

since perimeter=L+W+L+W, you would 99 + 99 which equals 198, then subtract 198 from 314 which equals 116 then divide that by two which equals 58.
