One side of the triangle is 25 centimeters 4 centimeters more than the second side and 5 cm less than the third, calculate the perimeter of this triangle.
Find the value of the second side of the triangle, for this you need to reduce the value of the first side of the triangle by 4 cm:
25 cm – 4 cm = 21 cm – the value of the second side of this triangle;
Find the value of the third side of the triangle, for this you need to increase the value of the first side of the triangle by 5 cm:
25 cm + 5 cm = 30 cm – the value of the third side of this triangle;
Let’s find the value of the perimeter of this triangle, for this it is necessary to add the values of all sides of the triangle:
25 cm + 21 cm + 30 cm = 76 cm – the value of the perimeter of the triangle.
Answer: 76 cm is the value of the perimeter of the triangle.
