Algebra.Com's Answer #78919 by bucky(2189)![]() ![]() ![]() You can put this solution on YOUR website! The area of a triangle is found by using the formula: \n" ); document.write( ". \n" ); document.write( "A = (1/2) * b * h \n" ); document.write( ". \n" ); document.write( "where A is the area, b is the length of the base, and h is the height or the altitude of \n" ); document.write( "the triangle. \n" ); document.write( ". \n" ); document.write( "We must stay in the same system of units. In this problem the base and altitude are in \n" ); document.write( "feet so the area will be in square feet. \n" ); document.write( ". \n" ); document.write( "All you have to do now is substitute the values into the equation to get: \n" ); document.write( ". \n" ); document.write( "A = (1/2) * 22 * 7 \n" ); document.write( ". \n" ); document.write( "Since (1/2) times 22 is 11, the area is: \n" ); document.write( ". \n" ); document.write( "A = 11 * 7 = 77 square feet \n" ); document.write( ". \n" ); document.write( "Hope this helps you to understand the problem and how to solve it. \n" ); document.write( " \n" ); document.write( " |
