Question 268711
Start with:
{{{A = (1/2)b*h}}} for the area of a triangle. Substitute {{{b = sqrt(30)}}} and {{{h = sqrt(6)}}} to get:
{{{A = (1/2)(sqrt(30))*(sqrt(6))}}} Substitute {{{sqrt(30) = sqrt(5)*sqrt(6)}}}
{{{A = (1/2)(sqrt(5))*(sqrt(6))*(sqrt(6))}}} Substitute {{{6 = sqrt(6)*sqrt(6)}}}
{{{A = (1/2)(6)*sqrt(5)}}} Simplify.
{{{highlight(A = 3sqrt(5))}}} Sq. meters.
