Option A
The width of the rectangular prism is 13 units less than the length
<em><u>Solution:</u></em>
Given that, the length, width, and height of a rectangular prism is a, (a-13), and (a+13) respectively
From given question,
Length of rectangular prism = a
Width of rectangular prism = a - 13
Height of rectangular prism = a + 13
We have to find which statement best describes (a - 13)
From given (a - 13) means Width of rectangular prism
Therefore,
Width of rectangular prism = (a - 13)
We know that from given "a" denotes Length of rectangular prism
So we get,
Width of rectangular prism = (Length of rectangular prism - 13)
So the above expression means that width is 13 units less than length
So option A is correct. The width of the rectangular prism is 13 units less than the length
<em><u>Let us also analyse the options one by one</u></em>
<em><u>a.) the width of the rectangular prism is 13 units less than the length</u></em>
Which is written mathematically as,
width = length - 13 = a - 13
So this option is correct
<em><u>b. the height of the rectangular prism is 13 units more than the length</u></em>
Which is written mathematically as,
height = 13 + length = 13 + a
So this option does not describes (a - 13)
<em><u>c. the width of the rectangular prism is 13 units less than the height</u></em>
Which is written mathematically as,
width = height - 13 = a + 13 - 13 = a
So this option does not describes (a - 13)
<em><u>d. the length of the rectangular prism is 13 units less than the height</u></em>
Which is written mathematically as,
length = height - 13 = a + 13 - 13 = a
So this option does not describes (a - 13)
