Review

The dimensions of this trapezoid are a = 5, b = 5, c = 7, d = 4, and h = 4. What is the area?

51% Answer Correctly

	32\(\frac{1}{2}\)
	9
	18
	17\(\frac{1}{2}\)

Solution

The area of a trapezoid is one-half the sum of the lengths of the parallel sides multiplied by the height:

a = ½(b + d)(h)
a = ½(5 + 4)(4)
a = ½(9)(4)
a = ½(36) = \( \frac{36}{2} \)
a = 18

A(n) __________ is to a parallelogram as a square is to a rectangle.

51% Answer Correctly

	quadrilateral
	trapezoid
	rhombus
	triangle

Solution

A rhombus is a parallelogram with four equal-length sides. A square is a rectangle with four equal-length sides.

If BD = 17 and AD = 22, AB = ?

76% Answer Correctly

	8
	5
	19
	1

Solution

The entire length of this line is represented by AD which is AB + BD:

AD = AB + BD

Solving for AB:

AB = AD - BD
AB = 22 - 17
AB = 5

Which of the following is not true about both rectangles and squares?

63% Answer Correctly

	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
	the area is length x width

Solution

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 a = c = 1, b = d = 2, what is the area of this rectangle?

80% Answer Correctly

	2
	10
	48
	14

Solution

The area of a rectangle is equal to its length x width:

a = l x w
a = a x b
a = 1 x 2
a = 2
