Question

The perimeter of the scalene triangle is 54.6 cm. Which equation can be used to find the value of b if side a measures 8.7 cm? 8.7 + b = 54.6 17.4 + b = 54.6 26.1 + b = 54.6 34.8 + b = 54.6

Answer 1

Let a, b and c be the sides of the scalene triangle.

The perimeter of the triangle is :

P = a + b + c

Therefore :

54.6 = a + b + c

a = 8.7

b + c = 54.6 - 8.7 = 45.9

We want b :

b = 45.9 - c

The closest option is :

8.7 + b = 54.6
