What's the area of an equilateral triangle whose perimeter is 24 centimeters

Question

campbell_st · Answer

so if the perimeter is 24, and an equilateral triangle has all sides equal. 

then each side is 24/3 = 8 centimetres. 

so now you need to find perpendicular height using pythagoras' theorem 

|dw:1399963365254:dw|

find h

then you can find the area. 

hope it helps

Ok, building off what campbell_st said, each side is 8 cm. Using the Pythagorean Theorem, the length of the squared hypotenuse-the squared base=the square root of the height. 

$$8^{2}=64$$$$4^{2}=16$$$$64-16=48$$$$\sqrt{48}=6.92$$So, the height is 6.92 cm. The area of a triangle is; A=.5*h*b$$.5\times6.92\times8=27.71$$So, the area of the equilateral triangle is 27.71 cm. ^2
