The formula for the eres of a triangle is A=2/1bh what is h equal to in terms of a and b
Kisachek [45]
Actually the formula for the area of a triangle is A = 1/2bh.

First step: multiply both sides by 2, to get rid of the 1/2.

2A = bh

Now divide both sides by b.

2A/b = h or h = 2A/b

What is it??????????
spayn [35]

Hey! :)

Some things to note: When you bring a exponent to the numerator, you make it negative.

When you put an exponent to another exponent, you multiply the exponents together.

(\frac{3x^2y^5}{x^6y^2} )^4\\\frac{81x^8y^{20}}{x^{24}y^8}\\81x^8x^{-24}y^{20}y^{-8}\\\frac{81y^{12}}{x^{16}}

so that is your answer, please let me know if you need more of an explanation. :)
