Question

The expression to find the perimeter of a rectangle is 2(length + width). What is the perimeter, in units, of a rectangle of length fraction 1 over 5 unit and width fraction 1 over 2 unit? (1 point) fraction 1 and 2 over 5 units fraction 1 and 1 over 5 units fraction 4 over 7 unit fraction 2 over 7 unit

Answer 2

Answer: 1 2/5

Explanation:

If the length is 1/5 and the width is 1/2, we can substitute those numbers into the perimeter expression provided. Or, we can double each of them and then add them together, as I did to solve this.

Since 1/2 + 1/2 = 1 , we can quickly add the doubled length value of 1/5 , ( doubled is 2/5 ) to get our sum of 1 2/5
