A quadrilateral is a shape with four sides. The perimeter of a quadrilateral is the sum of the lengths of its four sides.
If the base of this triangle is 3 and the height is 7, what is the area?
| 44 | |
| 36 | |
| 10\(\frac{1}{2}\) | |
| 25 |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 3 x 7 = \( \frac{21}{2} \) = 10\(\frac{1}{2}\)
If a = -7 and x = -1, what is the value of a(a - x)?

To solve this equation, 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.)
a(a - x)
1(-7)(-7 + 1)
1(-7)(-6)
(-7)(-6)

The formula for the area of a circle is which of the following?
c = π d |
|
c = π d2 |
|
c = π r2 |
|
c = π r |
The circumference of a circle is the distance around its perimeter and equals π (approx. 3.14159) x diameter: c = π d. The area of a circle is π x (radius)2 : a = π r2.
