    Its 9.8 (approximately) are there supposed to be decimal points in those answers? if so you're right. Good job!

    2x^2 = (7sqrt2)^2 (pythagorean theorem) 2x^2=49*2 x^2=49 x=7 new area = x^2 = 49

    But then there is no point of even providing the info about origami, it should just say to find the area of a square with that side length. The intro was unnecessary

    yeah its because its a story problem and they are supposed to be confusing
