Length (a) – 12 cm;
Width (b) – 10cm;
Rpr. -? cm;
Sp. -? cm ^ 2.
It is known that the perimeter of a rectangle is found by the formula:
Rpr. = (a + b) * 2 = (12 + 10) * 2 = 22 * 2 = 44 (cm).
The area of the rectangle is found by the formula:
Sp. = a * b = 12 * 10 = 120 (cm ^ 2).
Answer: Rpr. = 44 cm; Sp. = 120 cm ^ 2.
