Today is day four of the problem of the week! We already covered trigonometry, algebra, and number theory, so I will devote today to geometry. Good luck!

Easy:

Take the following rectangle:

What is the area and perimeter of this rectangle? Since

*a*and

*p*were already used on the triangle, use

*b*for the area and

*q*for the perimeter (just move up a letter).

*b*= _____

*q*= _____

Medium:

First, determine the values of

*u*and

*q*.

*u*=

*n*÷ 1000

*q*=

*p*÷ 2

Now, take the following trapezoid, using these values:

What is the area of this trapezoid? Use

*a*for area.

*u*= _____

*q*= _____

*a*= _____

Hard:

Find the area

*t*of a regular polygon with

*x*

_{3}(

*b*-

*a*-

*c*) sides and a perimeter of

*q*. Round to the nearest hundredth.

*t*= _____

Good luck!
