B,C,D are all equivalent.
12 + n
if you substitute n for any whole number and simplify. you will find that 12+n does not equal any others. for example, i used 6 in place of n and all equations gives you 10 except 12+n
hope this helps!
In the diagram, the width of the given rectangle is 15 cm
<h3>Determining the width of rectangle</h3>
From the question, we are to determine the width of the given rectangle
In the given diagram, we can observe that
The length of the rectangle will contain 6 identical squares if arranged linearly
∴ Length of rectangle = 6 squares
From the given information,
Length of the rectangle = 18 cm
∴ Length of a square = 18 cm / 6
Length of a square = 3 cm
Also,
If arranged vertically, the width of the rectangle will contain 5 of the identical squares
∴ Width of the rectangle = 5 × 3 cm
Width of the rectangle = 15 cm
Hence, the width of the given rectangle is 15 cm
