Ok so area of a square is equal to the length of the side squared. So if we know the area we can take the square root to find the length of each side.
Square root of 6.25 = 2.5
So the answer is 2.5

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.
The area of any square (or other rectangle) is equal to the base times the height. So just measure the length of one side of the frame, then multiply that number by itself.

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.
This sounds like a MATH question i hope you dont CHEAT!
