If you look at the attached graphic, you will see that the altitude (or height) of an equilateral triangle is:
Height = side length * sq root (3) / 2
Area = side^2 * sq root (3) / 4
Answer:
25
Step-by-step explanation:
If h=2 it would be 2+3 which equals 5. Then multiply 5 by 5 and get 25.
Hope this helps :)
Multiply length times width to find the area. 6.5x11= 71.5

Be that unknown number X
Then we can write the following expression:
X + 4.7 = 8.1
<h2>X = 3.4</h2>
This is more or less how you write the question.
To solve it invert the 1/2 and multiply.
Which gives you 14 /8 whis is 1 3/4 cups.
