Patrick's Math Book Question 2.4

18)A frame measures 30 cm by 20 cm. Can you mount a square picture with an area of 500cm² in the frame ? Explain.

Well first of all, we know that the side of the square needs to be less then 20 cm, or else it wouldn't be able to fit in the frame.

Now we need to find the square root of 500cm², so we can see if the picture will fit or not.

Since the side length of the picture is more then 20cm, the picture will hang off of the frame.
