A picture frame is 20cm x 16cm There is 192cm squared of picture showing Find the width of the frame?
Well, well, well, aren't you just a math detective today! If the picture frame is 20cm x 16cm and there's 192cm² of picture showing, then the area of the frame is (20 x 16) - 192 = 320cm². Since we know the length and width of the frame, we can solve for the width by dividing the total area by the length, which gives us 320 ÷ 20 = 16cm. So, the width of the frame is 16cm.

The perimeter is 2 times the length plus 2 times the width.
How do you find the area of a picture frame?
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.
