Many correct answers!!
This is an Isosceles Triangle; thus, 4 sides, not 3.

Area = 1/2 base x height

If you know all three sides of ANY triangle, this is the formula:
Say the sides are "a", "b" and "c"
and "sqrt" means "square root of"
Area = sqrt [ (s)(s - a)(s - b)(s - c) ]
where s = (a + b + c) / 2
Calculate "s" first and then plug into the area formula
Example:
Triangle has sides 5, 7 and 10
s = (5 + 7 + 10) / 2 = 11
A = sqrt [ (11)(11 - 5)(11 - 7)(11 - 10) ]
= sqrt[ (11)(6)(4)(1) ]
=sqrt [ 264]
= 16.25

The formula for finding the area of a triangle is 1/2(bxh). That is one-half the base times the height.

A = 1/2 bh
when b = base and h = height

for right triangles, its (1/2)bh=A
and for others use hero's formula
Area = sqr[s(s-a)(s-b)(s-c)] where s = (a+b+c)/2 or perimeter/2
sqr= square root

(1/2)bh=A
When b=base and h=height.
Hope I could help!
