The area of a rectangle is Length times Width or "lw"

'; explain[1] = '#2

A triangle is .5bh ((Base * Height)/2)

'; explain[2] = '#3

The variables used for the area of a parallelogram are Base (b) and Height, h.

'; explain[3] = '#4

The area of a rhombus is found by using the length of the diagonals.

'; explain[4] = '#5

A trapezoid uses 3 variables: base1, base2, and Height or h.

'; explain[5] = '#6

The constant used in helping find the area of a circle is known as PI.

'; explain[6] = '#7

All polygons have a formula to help find their area. This formula is A=.5aP

'; explain[7] = '#8

To find the area of this hexagon we must use our formula A=.5aP. So first we find our variables. We already know that a=6. Now we find P. P=6*4 which equals 24 so our formula is A=.5*6*24. So our answer is Area = 72

'; explain[8] = '#9

To find the area of a part of a circle we must use another formula: A=(n/360)(PI*r^2). Our radius is 4 and the angle is 30 so we plug them in A=(30/360)(PI*4^2) which simplifies to 4PI/3

'; explain[9] = '#10

To solve a math problem you do not need to know the units you are working in. You just need to know that everything is measured in the same units. The only time you need to know the units is when doing special functions on circles (you might need to know if you are working in radians or degrees).
