Question

the perimeter of an equilateral triangle is 60 m, find altitude

Answer 1

Answer:

20√3

Step-by-step explanation:

perimeter = 3 x side

60 = 3a

a = 60/3

a = 20 ---------------------1

AREA = √3/4 x a2

=100√3

also,

AREA OF TRIANGLE = 1/2 x base x height

therefore,

100√3 = 10 x height

height = 100√3/10

height = 10√3------------------------ANSWER.
