One of the sides of the quadrangle is 8 cm. The second side is 3 times larger than the first
One of the sides of the quadrangle is 8 cm. The second side is 3 times larger than the first, and the third is 7 cm smaller than the second and 9 centimeters larger than 4. Calculate the perimeter of the quadrilateral.
We will solve this task in steps and explain each of them in detail.
1) 8 * 3 = 24 centimeters – the length of the second side, since it is 3 times larger than the first side, and the first side is 8 centimeters;
2) 24 – 7 = 17 centimeters – the length of the third side, since it is 7 centimeters less than the second side, and the second side is 24 centimeters;
3) 24 – 9 = 15 centimeters – the length of the fourth side, since it is 9 centimeters less than the second side, and the second side is 24 centimeters;
4) 24 + 17 + 15 + 8 = 64 centimeters – the perimeter of the quadrangle.
Answer: 64 centimeters.
