The area of the rectangle in standard form is
Explanation:
Given that the length of the rectangle is
The width of the rectangle is
We need to determine the area of the rectangle.
The area of the rectangle can be determined using the formula,
Substituting the values of length and width in the formula, we get,
Multiplying the terms, we get,
Adding the like terms, we have,
Thus, the area of the rectangle in standard form is
Answer:

Answer:
3 sides
Step-by-step explanation:
Interior angle = {n - 2}{180/n}
60 = {n - 2}{180/n}
Cross multiply
60n = {n - 2}180
Dividing through by 60
n = (n - 2)3
n = 3n - 6
3n - n = 6
2n = 6
n = 6/2
n = 3
That statement is true. According to the Vertical Angles Postulate, if two angles are vertical angles, then they are congruent (have equal measures).
