What is the perimeter of a triangle with the side lengths 4 cm, 6 cm, and (3y-2) cm?

1 answer:

7 0

Answer:

Step-by-step explanation:

P = 4 + 6 + (3y - 2) Remove the brackets

P = 10 + 3y - 2 Combine

P = 8 + 3y

Note 3y must be less than 8. That's because 2 sides of any triangle must be larger than the 3rd side or else you don't have a triangle.

In this question, first we have to see how many feets are in 1 yard .

And there are 3 feets in 1 yard.

So in 3 yards, there are 9 feets

Therefore we will get

$\frac{1}{6}*3 yards= \frac{1}{6} * 9 feet = 1.5 feet$

Therefore the answer of the given question is 1.5 feet.
