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

63% Answer Correctly

the lengths of all sides are equal

the area is length x width

all interior angles are right angles

the perimeter is the sum of the lengths of all four sides
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).

2

Which of the following is not a part of PEMDAS, the acronym for math order of operations?

91% Answer Correctly

pairs

addition

exponents

division
Solution

When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)

3

If the base of this triangle is 8 and the height is 7, what is the area?

59% Answer Correctly
17\(\frac{1}{2}\)
60
28
45\(\frac{1}{2}\)
Solution

The area of a triangle is equal to ½ base x height:

a = ½bh
a = ½ x 8 x 7 = \( \frac{56}{2} \) = 28

4

If BD = 10 and AD = 20, AB = ?

76% Answer Correctly
10
3
14
11
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 = 20 - 10
AB = 10

5

The dimensions of this cube are height (h) = 5, length (l) = 1, and width (w) = 9. What is the volume?

83% Answer Correctly
108
45
128
160
Solution

The volume of a cube is height x length x width:

v = h x l x w
v = 5 x 1 x 9
v = 45
