Answer:
Hey ARNA (Pink Panther)!
I didn't know that you use this app
Any ways the answer is according to me--
a) Two simple machines are-- wedge and lever (2nd class lever)
b) The 2nd cls lever is wheelbarrow where the load is located between the fulcrum and effort.
And the wedge is looking like a structure like axe and it is is formed when two inclined planes are joined together in such a manner that one end is sharp and other is blunt
