Parallelogram perimeter HKTR 32cm find the sides of the parallelogram if the difference between the two sides is 9cm.

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 the difference between the two sides of the parallelogram is 9 cm, and its perimeter is 32 cm.

We denote one pair of sides as x cm, then we write the length of the second pair of sides as (x + 9) cm.

P = 2 (a + b);

2 (x + (x + 9)) = 32;

x + x + 9 = 32: 2;

2x + 9 = 16;

2x = 16 – 9;

2x = 7

x = 7: 2;

x = 3.5 cm is the length of one pair of sides of the parallelogram, then 3.5 + 9 = 12.5 cm is the length of the second pair of sides.
