You have to use the Pythagorean theorem but there is a little twist here since a square has has equal sides. So: x^2+x^2=8 2x^2=8 2/2x^2=8/2 x^2=4 √x^2=√4 x=2 The side of the square is 2. So now the area of a square is: Side×Side 2×2=4 The area of the square is 4 centimetres
If there were 1200 people, and 65 percent were women, that means the rest of the crowd are men, which is 35 percent. By multiplying 35 percent by the overall population, 1200, (1200*35/100), you'll get 420 men.
