The sum of the three sides is expressed in centimeters and the perimeter in decimetres and centimeters. Let’s convert the values of the perimeter to centimeters. 1 decimeter is equal to 10 centimeters.
7 dm 3cm = 7 * 10 cm + 3 cm = 73 cm.
We subtract the sum of three sides from the perimeter, we get the length of one side of the quadrilateral.
73 cm – 48cm = 25 cm.
Answer: the length of the side of the quadrangle is 25 cm.
