Question 489405
They're both squares.
n2+(n+2)2=148
n2+n2+4n+4=148
2n2+4n-144=0
n2+2n-72=0
*[invoke quadratic "x", 1, 2, -72 ]
Throwing out the negative answer, we get the width and length of the smaller square to be 7.544003745 cm, and the width and length of the larger square to be 9.54400374531753 cm..
