Question 73740
{{{Area=(base*height)/2}}}Use this to find the height
{{{100a^3b=(20a^2*height)/2}}}Solve for height by multiplying both sides by {{{2/20a^2}}}
{{{(2/cross(20)a^cross(2))100a^3b=height}}}compute 2(100/20)=10 and divide exponents by subtraction
{{{height=10ab}}}Simplify
Check:
{{{Area=(base*height)/2}}}Use this to check
{{{100a^3b=(20a^2*10ab)/2}}}
{{{100a^3b=(200a^3b)/2}}}
{{{100a^3b=100a^3b}}}Works
