The area of a right triangle is 81 square
meters. The height is twice as long as
the base.
To find the area of a triangle, use the
1
following formula:a bh
2.
where b is the base and h is the height.

the correct answer is b.

this is because an open circle means < or > & since the line goes left it is < -3.

the next one has a filled circle so it can only be ≥ or ≤ and since the line goes right from 1 it is ≥ 1

hope that
