I"m mirroring it through absolute proof. Equilateral triangle both side are same in size & same angel.It"s provided with the sides of 10 inch & elevation 7 inches. I don"t have 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 usage this formula,

where "a" is 10. Therefore the aramuseum.org come=43.3,which is 44.

So the correct answer is=44 inches.

* * * * *

Mostly correct, but:

43.3 should be rounded to 43, no 44.The devices for the area have to be square inches, no inches.
