Answer:
9 inches
Step-by-step explanation:
Let's take the dimension of the picture first
Area of the picture = 5 * 7
= 35 square inches
Now, we'll subtract this are from the combined area of the picture and the frame
Combined area = 80 square inches
80 - 35 = 45
Therefore, the area of the frame is 45 square inches
Since the width is uniform,
The number which when multiplied by 5 gives 45 is...........
9
Hence, the width of the frame is 9 inches
