Between which two consecutive whole numbers does the length of the diagonal fall? Which whole number is it closer to? Use the drop-down menus to show your answer.

4 and 5, closer to 4

Step-by-step explanation:

From the diagram above,

length of the diagonal = √18

√18 = 4.2426406871192

√18 is between 4 and 5

√18 is more than 4 by .2426406871192 but not up to 5

Rounding up 4.2426406871192 to an 1 significant figure,

We have 4

This means, the length of the diagonal, √18 is between 4 and 5 but it is closer to 4

i think the answer is b

2y+y=5

add 2y and y
