Question

The perimeter of a triangle is 26 feet. The second side is twice as long as the first. the third side is 1 foot longer than the second side. What is the length of the 3 sides?

Answer 1

5, 10 and 11 feet.

Explanation:

Let length of first side be x feet then

second side = 2x feet

third side = 2x + 1 feet.

So we have the equation:

x + 2x + 2x + 1 = 26

5x + 1 = 26

5x = 25

x = 5 feet.

So first side = = 5 feet, second = 10 and third = 11 feet.
