I'm showing it with absolute proof. Equilateral triangle both side are same in size & same angel.It's given with the sides of 10 inches & height 7 inches. I don't need to count the height(7),just use side(10).The formula is=
Area of a equilateral triangle="root over of 3" /4 * "a square"
Now I use this formula,
where "a" is 10. So the answers come=43.3,which is 44.
So the Correct answer is=44 inches.
* * * * *
Mostly correct, but:
- 43.3 should be rounded to 43, not 44.
- The units for the area should be square inches, not inches.
