Question

a square folded in half to form a rectange. if the resulting rectangle has a perimeter of 15 inches what is the area of the original square. How do I figure this out

Answer 1

let the length of the square be x.
then the perimeter of the rectangle formed should be:
x + x + 1/2 x + 1/2x = 15
thus 3x = 15
x =5
the area of the square is 25 inches square.
