For a rectanglar picture, measure the length and width of the space where the picture will fit inside the frame and multiply the two measurements together to obtain the area. Example: 7 inches x 9 inches = 63 square inches. For a circular picture, measure the diameter of the space where the picture will fit inside the frame then multiply the radius (half the diameter) by itself and by pi (3.14). Example: for 6 inch diameter, 3.14 x 3 inch x 3 inch = 28.26 square inches.
