Answer:
Option first is the answer.
Step-by-step explanation:
For finding the are of a right angle triangle, we use the base and the height of the triangle. The height is the right angle leg of the triangle. Hypotenuse is not considered here.
In the given diagram, the base or 'b' is = 10 units
And the height or 'h' is = 24 units
Area of a right triangle is given as :
[tex]A=\frac{bh}{2}[/tex]
So, in the given options the correct option is : Option first.
[tex]A= \frac{10*24}{2 }[/tex] or [tex]\frac{1}{2}(10*24)[/tex]
