One side of the triangle is 6cm, the other. 4 times longer than the first, and the third is 3 cm shorter than the second. find the perimeter of the triangle.

Find the value of the second side of the triangle, for this you need to increase the value of the first side of this triangle by four times:

6 cm * 4 = 24 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 reduce the value of the second side of this triangle by 3 cm:

24 cm – 3 cm = 21 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 this triangle:

6 cm + 24 cm + 21 cm = 51 cm – the value of the perimeter of this triangle.

Answer: 51 cm is the value of the perimeter of this triangle.
