From the solutions above, we know that the sides CP and AP are 3 and 4 respectively because of the properties of medians that divide cevians into 1:2 ratios. We can then proceed to use the heron's formula on the middle triangle EPD and get the area of EPD as 3/2, (its simple computation really, nothing large).Resources Aops Wiki 2003 AMC 10B Problems Page.

And let the dimensions be a * b, then we have one side will have a+1 posts (including corners) and the other b+1 (see example diagram below with a=4 and b=3). The total number of posts is 2 (a+b)=20. Solve the system b+1=2 (a+1) and 2 (a+b)=20, We get: a=3 and b=7.Solution 1. Using the area formulas for an equilateral triangle and regular hexagon with side length , plugging and into each equation, we find that . Simplifying this, we get. Solution 2. The regular hexagon can be broken into 6 small equilateral triangles, each of which is similar to the big equilateral triangle.

Let the population of the town in 1991 be p^2. Let the population in 2001 be q^2+9. Let the population in 2011 be r^2. 141=q^2-p^2= (q-p) (q+p). Since q and p are both positive integers with q>p, (q-p) and (q+p) also must be positive integers. Thus, q-p and q+p are both factors of 141.A circle of radius 5 is inscribed in a rectangle as shown.
