The perimeter of a scalene triangle is 14.5 cm. The longest side is twice that of the shortest side. Which equation can be used
wel

Answer:

9.3 + b = 14.5

Step-by-step explanation:

Longest side of ∆ = 2a = 6.2 cm

If the shortest side is, a, and we are told that the longest side is twice the shortest side, therefore, length of shortest side is

The sum of the 3 sides = perimeter = 14.5 cm

Thus,

a + 2a + b = 14.5 cm

Plug in the values of a and b

3.1 + 6.2 + b = 14.5

The equation that can be used to find the side lengths is 9.3 + b = 14.5
