fenix001 [56]
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 .

AnnyKZ [126]
 set up a ratio to find the length:

15/12 = DE/16

cross multiply the 15 & 16:
15 * 16 = 240

divide that by 12 to get DE

240 / 12 = 20

DE = 20
