Which of the following is not true about both rectangles and squares?
the area is length x width |
|
the perimeter is the sum of the lengths of all four sides |
|
all interior angles are right angles |
|
the lengths of all sides are equal |
A rectangle is a parallelogram containing four right angles. Opposite sides (a = c, b = d) are equal and the perimeter is the sum of the lengths of all sides (a + b + c + d) or, comonly, 2 x length x width. The area of a rectangle is length x width. A square is a rectangle with four equal length sides. The perimeter of a square is 4 x length of one side (4s) and the area is the length of one side squared (s2).
If BD = 22 and AD = 29, AB = ?
| 6 | |
| 7 | |
| 14 | |
| 13 |
The entire length of this line is represented by AD which is AB + BD:
AD = AB + BD
Solving for AB:AB = AD - BDIf a = 4, b = 9, c = 6, and d = 9, what is the perimeter of this quadrilateral?
| 16 | |
| 21 | |
| 28 | |
| 12 |
Perimeter is equal to the sum of the four sides:
p = a + b + c + d
p = 4 + 9 + 6 + 9
p = 28
On this circle, a line segment connecting point A to point D is called:
circumference |
|
radius |
|
chord |
|
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 side x = 11cm, side y = 10cm, and side z = 9cm what is the perimeter of this triangle?
| 25cm | |
| 26cm | |
| 24cm | |
| 30cm |
The perimeter of a triangle is the sum of the lengths of its sides:
p = x + y + z
p = 11cm + 10cm + 9cm = 30cm
