The correct answer is: " 784 in² " . _________________________________________ {or; write as: " 784 sq. inches " .}. _________________________________________ When the side is doubled (in this case, 4 is doubled; 4 * 2 = 8} ; the area is increased by 2² times; that is, by 4 times; so, the area is: (196 sq. in) * 4 = 784 sq inches . _________________________________________
Oh I get this. So what you have to do is leave the same denominator and just count. Once a fraction has the same numerator and denominator that means it is a whole number.
