Answer:
The perimeter of a rectangle is equal to the sum of all four sides. If the length of the rectangle is 3 more than the width, we can express the perimeter as 2width + 2(width+3). This simplifies to 2width + 2width + 6, which is equal to 58. This can be simplified to 4width + 6 = 58, or 4width = 52. Dividing both sides by 4 gives us width = 13.
Since the width of the rectangle is 13 cm, the length is 3 more than this, or 13+3 = 16 cm. So the dimensions of the rectangle are 13 cm by 16 cm.
