Question

PLEASE HELP
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 .....

Answer 1

An equilateral triangle has three equal sides and three equal angles

The perimeter of an equilateral triangle is equal to

P=3b

b is the length side of an equilateral triangle In this problem we have

P= 29.4

Substitute and solve for b

29.4 =3b

Then divide by  both sides

b=29.4/3

b=9.8 cm

hope this helped :)
