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)

click here to solve for x

x=22

22/2=11

(22-9)=13

The lengths of the three sides of the triangle are 11, 13 and 22.
