Question

The area of a rectangle is greater than or equal to 154 square centimeters. The width of the rectangle is 12 centimeters and the length is x centimeters. Select the possible value(s) of x.

x=12

x=12.5

x=13

x=13.5

Answer 1

13.5

Explanation:

The answer is 13.5 because it is greater than 154 and even though 13 is still higher than 154, 13.5 is the highest when multiplied by 12.

Answer 2

Answer: 13 & 13.5

Step-by-step explanation: Since the answer to this can be more than one number, I'll just list off each of these answers and find the possible value.

12x
`\geq` 154

12x12=144

144 < 154 (this doesn't work!)

12x12.5=150

150 < 154 (this doesn't work either!)

12x13=156

156 > 154 (this works!)

12x13.5=162

162 > 154 (this works as well!)
