Answer:
21 cm
Step-by-step explanation:
A rectangle is shown. The rectangle will be enlarged by a scale factor of 1.5.
2 cm
5 cm
What will be the perimeter of the enlarged rectangle?
we find the two measures of the triangle
2 * 1.5 = 3 cm
5 * 1.5 = 7.5 cm
To find the perimeter of a rectangle, add the lengths of the rectangle's four sides
3 + 3 + 7.5 + 7.5 =
21 cm
