One side of the triangle is 35% of its perimeter, the other 40%. How long is the third side of this

One side of the triangle is 35% of its perimeter, the other 40%. How long is the third side of this triangle if its perimeter is 350 cm?

1) Calculate 35% of 350 and find out the length of the first side of the triangle:

350: 100 * 35 = 3.5 * 35 = 122.5 cm.

2) Calculate 40% of 350 and find out the length of the second side of the triangle:

350: 100 * 40 = 3.5 * 40 = 140 cm.

3) Calculate the length of the third side of the triangle. To do this, subtract the sum of the lengths of the other two sides from the perimeter:

350 – (122.5 + 140) = 350 – 262.5 = 87.5 cm.

Answer: The length of the third side of the triangle is 87.5 cm.
