If the total area of a picture measuring 10 inches by 12 inches plus a meeting of a uniform width surrounding the picture is 224 square inches, the width of the matting

The width of the matting is 4 inches.

Step-by-step explanation:

Since we are given the area of the picture including the frame we can use the formula for the Area of a rectangle to solve this problem.

since the picture frame has a uniform width we can use the variable x and plug in the values in the formula above. We then solve for x to find out the width of the matting.

.....use distributed multiplication

.... subtract 224 on both sides

Now we have a quadratic equation which we can use the quadratic formula to solve.

After Solving the Quadratic Equation we are given two values, but since our answer cannot be a negative, then the only valid answer is 4 in . So the width of the matting is 4 inches.
