The length of the rectangle is 14 cm, the area is 98 cm 2, calculate the width and perimeter.

1) A rectangle is a quadrangle in which two opposite sides are equal and all four corners are the same. The long side of the rectangle is called the length of the rectangle (a), and the short side is called the width of the rectangle (b).
The area of a rectangle is the space bounded by the sides of the rectangle, that is, within the perimeter of the rectangle. Formula for the area of a rectangle through two sides: S = a · b.
2) By condition, the length is a = 14. Using the formula from point 1, we get: 98 = 14 * b; b = 7 cm.
3) P = 2 (a + b) = 2 * 14 + 2 * 7 = 42 cm.
