Answer:
Scalene, right triangle
Step-by-step explanation:
its a scalene triangle because all the sides are different, and a right triangle because the box in the corners is what shows whether the angle is a right angle or not.
Hope that makes sense.
Area = base × height
31.5 = base × 6.3
base = 5 ft
3 root 7 the 1st one
the first one cant be a triangle
im pretty sure the second one can
the third one can
im pretty sure the fourth one cant
