If the base of this triangle is 3 and the height is 2, what is the area?
| 3 | |
| 49 | |
| 35 | |
| 44 |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 3 x 2 = \( \frac{6}{2} \) = 3

On this circle, line segment CD is the:
radius |
|
chord |
|
circumference |
|
diameter |
A circle is a figure in which each point around its perimeter is an equal distance from the center. The radius of a circle is the distance between the center and any point along its perimeter. A chord is a line segment that connects any two points along its perimeter. The diameter of a circle is the length of a chord that passes through the center of the circle and equals twice the circle's radius (2r).
If a = c = 1, b = d = 9, and the blue angle = 74°, what is the area of this parallelogram?
| 9 | |
| 16 | |
| 45 | |
| 6 |
The area of a parallelogram is equal to its length x width:
a = l x w
a = a x b
a = 1 x 9
a = 9
