Question #169948

A = 1/2 (b+c)h

rearrange the formula to highlight the heigh

Expert's answer

"A=\\frac{1} {2} (b+c) h"

Multiply both sides by 2 to do away with a half;

"2\u00d7A=(b+c)h"

Divide both sides by "(b+c)" so as to remain with the height ;

"h\\frac{(b+c) }{(b+c)} =\\frac{2A} {(b+c)}"

The "(b+c)" on the numerator and denominator will cancel out making the remainder to be ;

"h=\\frac{2A}{(b+c)}"
