What will be the perimeter and area of the rectangle below if it is in large using a scale factor of 7.5 width 6 cm length 8 cm
To find the new dimensions of the rectangle after being enlarged by a scale factor of 7.5, we multiply each of the original dimensions by 7.5.
Width of the enlarged rectangle: 6 cm * 7.5 = 45 cm
Length of the enlarged rectangle: 8 cm * 7.5 = 60 cm
The perimeter of a rectangle is calculated by adding all four sides. In this case:
Perimeter = 2 * (Width + Length) = 2 * (45 cm + 60 cm) = 2 * 105 cm = 210 cm
The area of a rectangle is calculated by multiplying the width and length. In this case:
Area = Width * Length = 45 cm * 60 cm = 2700 cm²
Therefore, the perimeter of the enlarged rectangle is 210 cm and the area is 2700 cm².
