The area of the following equilateral triangle is 62.4 square feet that is he height
Vikentia [17]

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

An 8 foot square floor is to be covered with square tiles measuring 8 inches on each side. If each tile costs 50 cents, how much
wariber [46]

9514 1404 393

Answer:

  (c) $72

Step-by-step explanation:

Each tile is 8/12 ft = 2/3 ft on a side. Then 8/(2/3) = 12 tiles will fit along each edge of the square area to be tiled. That is ...

  12 × 12 = 144

tiles will be needed to cover the area.

The cost of 144 tiles at $0.50 each is ...

  (144)($0.50) = $72.00
