Question:
If the area of a square is 144 cm%5E2 ,find the length of its diagonal.
-------------------------------------------------
Answer:
The diagonal of a square is sqrt%282%29 times longer than its side.
A+=+s%5E2, where A = area and s = side
s%5E2+=+144
s+=+sqrt%28144%29+=+12
Therefore, diagonal = highlight%2812sqrt%282%29+cm%29
