I can be little confident because if it was just 0.7 then it would be I am not confident at all. This decimal is more than 0 so it would be a little and not a lot.
16.75 square yards because area of a triangle is half the base times the height. 40.2÷4.8 is 8.375. Since that is half the base, multiply by two. 8.375×2 is 16.75. Hope that helps! :D
