Question 18, 2.4 on page 79
18. A frame measures 30 cm by 20 cm. Can you mount a square picture with an area of 500 squared cm in the frame? Explain.
= 30 x 20
So to find the sides of the picture, you have to find the square root of 500 which is 22.36.
One side of the picture is too big for the frame so the answer is no, it can't fit in the frame.
