Question

Suppose the area of a square plaque is 169 square inches. What is the length of each side of the plaque?

Answer 1

Area of a square = s^2 where s is the side length


So A = s^2, but we know that A = 169, so 169 = s^2


Take the square root of both sides and flip the equation to get s = 13. So the length of each side of the square is 13 inches.


Note: 13^2 = 169

Answer 2

\[\sqrt169\]\[10\sqrt69\]

Answer 3

not sure how you're getting that figure elizated

Answer 4

well the area of a square is x(x) so the sqrt of the area would be a side length.

Answer 5

exactly, but \[\large \sqrt{169}=\sqrt{13^2}=13\]

Answer 6

since \[\large 13^2=169\]

Answer 7

oh woops. sorry i didn't do this right. sorry. ignore my answer... jim is the right one. thanks for pointing that out.
