US estimates suggest that 4.7 square miles of Hiroshima were destroyed.
First, take the square root, to get the length of a side. Then (because of Pythagoras), multiply the length of the side by the square root of 2.First, take the square root, to get the length of a side.

With the available information all that can be said is that the area of the second square will be less than that of the first. The question cannot be answered in any meaningful way without further information. For example, do the vertices of the second square lie on the sides of the first? How far from the vertices of the first? What angle is the second square rotated through?
A "metre" is the English [U.K.] spelling of "meter" (American.) A meter is approximately 39," just as our Yard is 36". A "square" measurement is an area defined by side 1 x side 2 of a "square," or in this case 39" X 39".
Convert everything to feet (dividing inches by 12), then multiply. Alternately, multiply first, that will give you square inches; then divide by 144 to convert to square feet.Convert everything to feet (dividing inches by 12), then multiply.

About 4.7 square miles.
the first atomic bomb leveled nothing. That was exploded at the Trinity test site. The first bomb used in war was at Hiroshima Japan, and pretty much destroyed everything in a 3 mile radius. That is just over 7 square miles.
Hiroshima, august 6, 1945
There have only been two. So far. The first was Hiroshima.
Nagasaki (Japan), 9 August 1945
US estimates suggest that 4.7 square miles of Hiroshima were destroyed.
It destroyed approx 4.7 square miles of Hiroshima.

The first test was July 16, 1945 in Alamogordo, New Mexico. The Atomic bomb was also used to end Hiroshima on August 6, 1945 & to obliterate Nagasaki on August 9, 1945.
The bomb dropped on Hiroshima totally destroyed everything in a 1.6 km radius, a total of 12 km2 was destroyed. 80 000 people were killed by the blast and resulting firestorm, with another 80 000 dieing later from after effects.
It was first organised in atomic number as they are organised in atomic mass now.
Nagasaki (Japan): 9 August 1945.
