The length of one side of the triangle is 40% of the perimeter, the length of the other side is 0.35 of the perimeter

The length of one side of the triangle is 40% of the perimeter, the length of the other side is 0.35 of the perimeter, and the length of the third side is 6.2 cm. Find the perimeter of the triangle.

Let’s find what part of the perimeter is the first side of the triangle:

40/100 = 0.4

Since a triangle has only three sides, you can now find out how much of the third side is:

1 – 0.4 – 0.35 = 1 – 0.75 = 0.25 = 1/4

Since the third side of the triangle is equal to a quarter of the perimeter, the perimeter can be found by multiplying its length by 4:

6.2 * 4 = 24.8cm

This means that the perimeter of the triangle is 24.8 cm
