One side of triangle is 2 times the shortest side. The third side is 16 feet more than the shortest side. The perimeter is 80. Find all three sides.

Answer 1

Assume x to be the shortest side

one side= x

second side= 2s

third side= x+16

perimeter formula of triangle S₁ + s₂ +s₃ = P Plug the value in formula

x+2x+x+16=80

x=20

Answer 2

s repressents the length of the shortest side

2s represents the length of the second side

s + 16 represents the length of the third side

s + 2s + s + 16 = 80

Can you solve for s and answer?
