A quadrilateral is a shape with four sides. The perimeter of a quadrilateral is the sum of the lengths of its four sides.
If AD = 15 and BD = 7, AB = ?
| 16 | |
| 8 | |
| 4 | |
| 19 |
The entire length of this line is represented by AD which is AB + BD:
AD = AB + BD
Solving for AB:AB = AD - BDSimplify 8a x 7b.

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 x 7b = (8 x 7) (a x b) = 56ab
If the base of this triangle is 1 and the height is 9, what is the area?
| 66 | |
| 4\(\frac{1}{2}\) | |
| 27 | |
| 37\(\frac{1}{2}\) |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 1 x 9 = \( \frac{9}{2} \) = 4\(\frac{1}{2}\)
If a = c = 2, b = d = 7, what is the area of this rectangle?
| 16 | |
| 42 | |
| 18 | |
| 14 |
The area of a rectangle is equal to its length x width:
a = l x w
a = a x b
a = 2 x 7
a = 14
