Question

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

jim_thompson5910 · Answer

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

$$\sqrt169$$$$10\sqrt69$$

not sure how you're getting that figure elizated

anonymous · Answer

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

jim_thompson5910 · Answer

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

jim_thompson5910 · Answer

since $$\large 13^2=169$$
