1

If a = c = 7, b = d = 6, and the blue angle = 63°, what is the area of this parallelogram?

65% Answer Correctly
18
35
10
42
Solution

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

a = l x w
a = a x b
a = 7 x 6
a = 42

2

If a = 3, b = 2, c = 5, and d = 1, what is the perimeter of this quadrilateral?

88% Answer Correctly
24
30
11
18
Solution

Perimeter is equal to the sum of the four sides:

p = a + b + c + d
p = 3 + 2 + 5 + 1
p = 11

3

If side x = 6cm, side y = 6cm, and side z = 7cm what is the perimeter of this triangle?

84% Answer Correctly
29cm
33cm
32cm
19cm
Solution

The perimeter of a triangle is the sum of the lengths of its sides:

p = x + y + z
p = 6cm + 6cm + 7cm = 19cm

4

A right angle measures:

90% Answer Correctly

360°

90°

180°

45°
Solution

A right angle measures 90 degrees and is the intersection of two perpendicular lines. In diagrams, a right angle is indicated by a small box completing a square with the perpendicular lines.

Simplify (8a)(2ab) - (3a2)(7b).

62% Answer Correctly
37a2b
100ab2
-5a2b
100a2b
Solution

To multiply monomials, multiply the coefficients (the numbers that come before the variables) of each term, add the exponents of like variables, and multiply the different variables together.

(8a)(2ab) - (3a2)(7b)
(8 x 2)(a x a x b) - (3 x 7)(a2 x b)
(16)(a1+1 x b) - (21)(a2b)
16a2b - 21a2b
-5a2b
