Answer:
P = 9 cm
Step-by-step explanation:
The Perimeter of a Rectangle
Given a rectangle of dimensions W and L, the perimeter of the rectangle is:
P = 2W + 2L
Or, equivalently:
P = 2(W + L)
The dimensions of the icon for the mobile app are 1.5 cm and 3 cm, thus:
P = 2(1.5 cm + 3 cm)
P = 2(4.5 cm)
P = 9 cm
