A rectangular sticker is 4 millimeters wide and 3 millimeters tall. What is its area? (Hint: Use the formula a = l x w).
A.
12 millimeters squared
B.
7 millimeters squared
C.
14 millimeters squared
D.
25 millimeter
The area of a rectangle can be found by multiplying its length (l) by its width (w).
In this case, the width is 4 millimeters and the height is 3 millimeters.
The area (a) can be found using the formula:
a = l x w
Plugging in the values, we get:
a = 4 mm x 3 mm = 12 mm²
Therefore, the answer is:
A. 12 millimeters squared.
