The height of this triangle would be 10.4

In order to find this, you first must find the length of the sides. Using a manipulated formula for area of an equilateral triangle, we can determine the lengths of the side. Below if the formula.

S = \frac{2}{3}3^{\frac{3}{4}} \sqrt{A}

In this, S is the length of the side and A is the area. So we plug in and get:

S = \frac{2}{3}3^{\frac{3}{4}} \sqrt{62.4}

S = \frac{2}{3}3^{\frac{3}{4}} 7.89

S = 12

Now that we have the side as 12, we can use the Pythagorean Theorem to find the height. If you split a equilateral triangle down the middle, you are left with two right triangles. Using this right triangle, the hypotenuse would be 12, the first leg would be 6 (half of the base) and the height would be the other leg. So we plug in and solve.

a^{2} + b^{2} = c^{2}

6^{2} + h^{2} = 12^{2}

36 + h^{2} = 144

h^{2} = 108

h = 10.4

We have that:

10 people is 2$ of all newspapers readers, which total t. This means that:

0.02t = 10

t = \frac{10}{0.02}

t = \frac{1000}{2}

t = 500
