Textbook - Chapter 2.4 Page 79 Question 18

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

√500 = 22.36 cm

Picture = 22.36 cm

Frame = 30 cm x 20cm

No you cannot mount a square picture on the frame because one side of the picture is too big for the frame so it won't fit.
