WILL MARK BRAINLIEST One side of a triangle is twice as long as a second side. The remaining side is 3 larger than the second side. The perimeter is 39m. Find the length of each side.

Step-by-step explanation:

One side of a triangle is four centimeters longer than the shortest side. The third side of the triangle is twice as long as the shortest side. Find the length of all the sides if the perimeter is 40 centimeters.

Let x be the length of the shortest side.

Then the lengths of the other two sides are x + 4 and 2x.

The perimeter of the triangle is x + (x + 4) + 2x.

As the perimeter is 40, we have

x + (x + 4) + 2x = 40

Solving for x, we have

x+ x + 4 + 2x = 40

4x + 4 = 40

4x = 36

x = 9

So the length of the shortest side is 9 cm.

The lengths of the other two sides are:

x + 4 = 9 + 4 = 13 cm

2x = 2*9 = 18 cm
