Let's say we have a square whose sides all measure 14 inches. Determine to two decimal places the dimensions of the square that has twice the area of this square.

Answer :

The square measures 14 by 14
so the area = 14 x 14 = 196 square inches

Double the area:
196 x 2 = 392 square inches

To find one side of the square:
[tex] \sqrt{392} [/tex] = 19.80 inches (2 d.p.)
