If a 5 by 7 picture is enlarged by 150%, what is the new area?
35 * 1.5 = ______ square inches
A photograph that is 3 1/2 x 6 is to be enlarged so that the larger side is 15" find the perimeter of the larger photograph
To find the new area of a 5 by 7 picture when enlarged by 150%, you can follow these steps:
1. Determine the dimensions of the enlarged picture:
- Multiply the length by the enlargement factor: 5 x (1 + 150/100) = 5 x 2.5 = 12.5
- Multiply the width by the enlargement factor: 7 x (1 + 150/100) = 7 x 2.5 = 17.5
2. Calculate the area of the enlarged picture:
- Multiply the length by the width: 12.5 x 17.5 = 218.75
Therefore, the new area of the 5 by 7 picture when enlarged by 150% is 218.75 square units.
