Calculate the length of the side of the square to 1dp.​
Sveta_85 [38]

Answer:

72 cm

Step-by-step explanation:

You can solve this problem using the properties of the 45-45-90 right triangle. Assuming the 12 cm is a diagonal of the square, each side of the square can be modeled as x, and the diagonal will be x\sqrt{2}.

This means x\sqrt{2} =12, so  x=\frac{12}{\sqrt{2} }.

Next, to find the area of the square you take the square of any of its sides. Since x is the length of one side, and x=\frac{12}{\sqrt{2} } , you can square \frac{12}{\sqrt{2} } to get the area. This is equal to \frac{144}{2} or 72 cm.
