What is the area of an equilateral triangle with each side as 2 inches?

We use pythagoraeon theroome to find the height
see attachment

remember
for a right traingle
a²+b²=c²

legs are 1 and ?
hytponuse is 2
1²+?²=2²
1+?²=4
minus 1 both sides
?²=3
sqrt both sides
?=√3=height

area=1/2 times base times height
aera=1/2 times 2 times√3
area=√3 square inches

1- x^3-7x^2+4x+30

2-?

3- 15x^6-20x^5+10x^4

4- 18x^5y^4z
