Describe order of operation and give an example
ryzh [129]

Order of Operation is commonly referred to as PEMDAS, an acronym for "Please excuse my dear aunt Sally," which references the order in which operations should  be calculated when solving a math problem.

P = parentheses

E = exponent

M = multiply

D = divide

A = add

S = subtract

So you don't always have all of these components, but you consider the ones present in the problem in front of you.    If there is no multiplication, but there is division and a set of parentheses, then you FIRST solve what's inside the parentheses, then  you divide.    If you have some examples, I'll show you.

The coordinates of the vertices of a regular polygon are given. Find the area of the polygon to the nearest tenth.
alexandr1967 [171]

Answer:

The area is equal to 8\ units^{2}

Step-by-step explanation:

we have

A(0, 0), B(2, -2), C(0, -4), D(-2, -2)

Plot the figure

The figure is a square (remember that a regular polygon has equal sides and equal internal angles)

see the attached figure

The area of the square is

A=AB^{2}

<u><em>Find the distance AB</em></u>

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

substitute the values

AB=\sqrt{(-2-0)^{2}+(2-0)^{2}}

AB=\sqrt{(-2)^{2}+(2)^{2}}

AB=\sqrt{8}

AB=2\sqrt{2}\ units

<u><em>Find the area of the square</em></u>

A=(2\sqrt{2})^{2}

A=8\ units^{2}
