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 to find the side lengths if the longest side measures 6.2 cm? choose the correct answer. 6.2 + b = 14.5 9.3 + b = 14.5 12.4 + b = 14.5 18.6 + b = 14.5

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 to find the side lengths if the longest side measures 6.2 cm? choose the correct answer. 6.2 + b = 14.5 9.3 + b = 14.5 12.4 + b = 14.5 18.6 + b = 14.5

Answer

Explanation:

Step1: Identify the longest - side value

Given the longest side (2a = 6.2) cm.

Step2: Recall the perimeter formula

The perimeter of a triangle (P=a + b+2a), and (P = 14.5) cm. Since (2a = 6.2) cm, the equation for the perimeter becomes (6.2 + b=14.5).

Answer:

(6.2 + b = 14.5) (First option)
