Hello,
\n" ); document.write( "Yes, you got the right idea but missed an important value. Let's do step by step so it's clear.
\n" ); document.write( "We know the area of a triangle is 1/2(base x height) so we can plug in the values known as:
\n" ); document.write( "28=x(x)(1/2) Or rewritten as:
\n" ); document.write( "28=x^2/2 Multiply each side by 2 to get:
\n" ); document.write( "56=x^2 Square root each side to get:
\n" ); document.write( "x=sqrt 56 Or
\n" ); document.write( "x=7.48 inches (rounded off)
