Answer:
20 inches by 28 inches
Step-by-step explanation:
The current size of the picture is 5 inches by 7 inches
If we want to enlarge the picture by a factor of 4, the perimeter will also increase by the factor of 4.
New dimension = 4(old dimensions)
= 4(5 inches by 7 inches)
= 20 inches by 28 inches
Hence, the size of the enlarged picture is 20 inches by 28 inches.
This point represents the area when the length is 2 inches. Because the width is 2 less than the length, the width is
2-2 = 0
Therefore, the area is 0.
