In a quadrilateral ABCD side AB- x cm Express the other sides of this quadrilateral if BC is 3cm less than AB CD

In a quadrilateral ABCD side AB- x cm Express the other sides of this quadrilateral if BC is 3cm less than AB CD is 1, 125 times more than AB AD is 3cm more than CD P-10.2cm.

AB = x – by condition;
It is said that CB is 3 centimeters less than the AB side, which means the CB side = x-3;
The CD side is 1.125 times larger than the AB side, which means the CD side = 1.125 * x;
The AD side is 3 times larger than the CD side, so the AD side = 1.125x + 3;
By condition, it is said that the perimeter of the quadrangle is 10.2 centimeters. The perimeter is the sum of the lengths of all sides of the shape. Let’s make the equation:
x + (x-3) + 1.125x + (1.125x + 3) = 10.2;
4.25x = 10.2;
x = 10.2 / 4.25;
x = 2.4.
Answer: x = 2.4 cm.
