The figure is formed by a right triangle, a parallelogram with a height of 6 cm, and a square. temma found that the area of the figure is 34 cm2 and that the perimeter is 50 cm. which statement is true?

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0
