The formula for the area of a triangle is:
where B is the base of the triangle and h is the height
It appears that the height of the triangle is 5 units (not quite 4.5) and the base is 10 units.
Multiply these to get 50, and divide by 2 to get 25.
The area of the triangle should be 25 u²
Hope this helps! :)

Answer:
The length of the arc is 2.25 units.
Step-by-step explanation:
The circumference of a circle is , where r is radius of the circle.
Total angle of a circle in degree is 360°.
Length of central angle formula
Given that,
A circle has a circumference of 5 units.An arc in the circle has a central angle of 162°.
Then,
=2.25 units.
The length of the arc is 2.25 units.
