Problema Solution
one side of a triangle is half the longest side. the third side is 9 feet less than the longest side. the perimeter is 46. find all three sides
Answer provided by our tutors
perimeter equals to sum of all sides
let 'x' represent the longest side, then 'x/2' represents one of the other sides and 'x-9' represents the third side
46=x+(x/2)+(x-9)
x=22
22/2=11
(22-9)=13
The lengths of the three sides of the triangle are 11, 13 and 22.
