You can find the area of a triangle using the formula A=1/2bh, where b is the length of the base, and h is the height. Write the equation for b in terms of A and h.
so basically you want b= something remember the associative property of multiplication the equation is A=1/2bh put parenthasees a=(1/2)(b)(h) divide both sides by (1/2 times h) a/((1/2)(h))=b
