Question 1012103
The area of rectangle is given by the formula {{{a=b*h}}}. If both sides, base and height, are longer, then the equation is now {{{a=2b*2h}}} which equates to {{{4b*h}}}. This tells us we have four times the area of the original rectangle. Thus, {{{4*17=68}}}
Therefore, your answer is 68 {{{cm^2}}}
