In order to find the sides of a parallelogram, we will recall the properties of the sides of a parallelogram and the formula for finding the perimeter of a parallelogram.
It is known from the condition that one of the sides of the parallelogram is 2 times smaller than the other, and its perimeter is 48 cm.
We denote one pair of sides as x cm, then we write the length of the second pair of sides as 2x cm.
P = 2 (a + b);
2 (x + 2x) = 48;
x + 2x = 48: 2;
x (1 + 2) = 24;
3x = 24;
x = 24: 3;
x = 8 cm is the length of one pair of sides of the parallelogram, then 8 * 2 = 16 cm is the length of the second pair of sides.
