Answer:
45 square units.
Step-by-step explanation:
Applying the pythagoras theorem:
Base of the bigger triangle =
=
= 12 units
Area of a triangle is given by
× base × height
The area of the bigger triangle is
× 12 × 9 = 54 square units.
The area of the smallest triangle is
× (12 - 10) × 9 = 9 square units.
The area of the figure( required triangle) is 54 - 9 = 45 square units.
