Question #17088

Answer 1

37 cm

Explanation:

An equilateral triangle had 3 equal sides.
The perimeter is the distance around all three sides. so

`3 xx s = 111` where s equal one of the three sides.

Divide both sides by 3 to isolate and find the value of s

`( 3 xx s)/3 = 111/3` This gives

`s = 37`
