the length of each equal side is 10 ft

the length of the third side is 2 ft

let x be the length of the third side the equal sides are 4x + 2

given perimeter == 22, then

x + 4x + 2 + 4x + 2 = 22

9x + 4 = 22 ( subtract 4 from both sides )

9x = 18 ( divide both sides by 9 )

x = 2 and 4x + 2= 10
