<p>Does anyone know the answer of the question asking us to find area of triangle with x=o, y=O and y=x+80 ?? I got 3200...</p>
<p>you’re right on!</p>
<p>Can anybody explain why you get that result???</p>
<p>I don’t remember that… Is this international??</p>
<p>@doridoriiiii, if you draw a picture, you’ll see that the three lines make an isosceles right triangle with side length 80. Its area is 80*80/2 = 3200.</p>
<p>Don’t remember this question at all. I had the math dummy however. Describing in further detail would help.</p>
