The perimeter of a rectangular painting is 356 cm and the length is 97 what is the width?

Here's the formula of rectangle perimeter
p = 2l + 2w

To find the width, substitute the given information to the formula above
2l + 2w = p
2(97) + 2w = 356
194 + 2w = 356
2w = 356 - 194
2w = 162
  w = 162/2 
  w = 81

The width of the rectangle is equal to 81 cm

1 over 2 because the disc has a 50-50 chance on landing either side.
