The perimeter of a rectangle is equal to the sum of the lengths of all its sides. P = = a + b + a + b = 2 (a + b).
P = 2 (7.8 + 13.45) = 2 * 21.25 = 42.5 (cm).
The area of a rectangle is equal to the product of its length and width, or the product of its sides. S = ab.
S = 7.8 * 13.45 = 104.91 (cm ^ 2).
Answer. 42.5 cm; 104.91 cm ^ 2.
