Question

If the number of units = X and Area of rectangle = Z. What is the formula to find how many rows of units there are? 2. What is the formula to find the number of units per row?

a) Number of rows = Z/X
b) Number of rows = X/Z
c) Units per row = X/Z
d) Units per row = Z/X

Answer 1

Correct formulas for calculating rows and units per row in a rectangle are Number of rows = Area (Z) / Units per row, and Units per row = Number of units (X) / Number of rows, assuming the rectangle can be evenly divided.

Step-by-step explanation:

The question relates to finding the number of rows and the number of units per row in a rectangle, given the total number of units (X) and the area of the rectangle (Z). The correct formulas are:

• 
  
• 
  

To clarify, let's assume that the number of rows is represented by Y. If the total number of units (X) is evenly distributed into rows within the rectangle, you divide X by the number of rows (Y) to find the units per row (X/Y). Conversely, to find the number of rows given the number of units per row, you would divide the area (Z) by the units per row.

Therefore, the correct choices are:

1. 
   
3. 
   

Note that these formulas assume the rectangle can be divided into equal rows without any remaining units.
