The sum of the length of two unequal sideways of a rectangle is 8 cm, the length of one of them is 3 cm, it is necessary to draw this rectangle and calculate its perimeter, it is obligatory to draw

If the first side is 3 cm, then, knowing the sum of the two sides (8 cm), we find out the length of the second side 8-3 = 5 cm. The perimeter is calculated by adding all the sides. We have a rectangle so the opposite sides are equal. The perimeter is (3 + 5) * 2 = 16 cm.
