As here we are given with an equilateral triangle, whose side is 3 cm, and we need to find the height and area of the equilateral triangle. So, for this let's recall that, the area of any equilateral triangle with side a is given by ;
So, if we substitute a = 3, in our Formula, it will yield to



Now, as we know that, for any triangle we also have a formula that is ;
Now, Here as the triangle is equilateral, so it's base will just be same 3, and if we let height be H, so we will be having

Answer:
Step-by-step explanation:
Let x represent the number of oxen. Then the number of ducks is 22-x and the number of legs is ...
4x +2(22 -x) = 72
2x +44 = 72 . . . . . . . simplify
x +22 = 36 . . . . . . divide by 2
x = 14 . . . . . . . . . subtract 22; the number of oxen
22-x = 8 . . . . . the number of ducks
There are 8 ducks and 14 oxen in the barn.
