Question

Keaton drew an equilateral triangle on the computer. if the perimeter of the triangle is 29.4 centimeters, the length of a side of the triangle is ____ centimeters.

Answer 1

29.4÷3=9.8 or just 10

Answer 2

Answer:

the length of a side of the triangle is $9.8\ cm$

Step-by-step explanation:

we know that

An equilateral triangle has three equal sides and three equal angles

The perimeter of an equilateral triangle is equal to

$P=3b$

where

b is the length side of an equilateral triangle

In this problem we have

$P=29.4\ cm$

Substitute in the formula and solve for b

$29.4=3b$

Divide by $3$ both sides

$b=29.4/3$

$b=9.8\ cm$
