Question

The perimeter of a triangle is 27.1 feet. The sides of the triangle measure 9.8 feet, 10.9, and x feet

Answer 1

Answer:

x = 6.4 feet.

Step-by-step explanation:

If a triangle has side lengths a, b, and c then its perimeter (P) will be given by ( a + b + c ).

Now, in this problem, the perimeter of a triangle is given to be 27.1 feet,

And its sides are 9.8 feet, 10.9 feet, and x feet.

Therefore, 27.1 = ( 9.8 + 10.9 + x )

⇒ 27.1 = 20.7 + x

⇒ x = 6.4 feet (Answer)
